* STRUCTURE DESCRIPTION
*
* Critnib is a hybrid between a radix tree and DJ Bernstein's critbit:
* it skips nodes for uninteresting radix nodes (ie, ones that would have
* exactly one child), this requires adding to every node a field that
* describes the slice (4-bit in our case) that this radix level is for.
*
* This implementation also stores each node's path (ie, bits that are
* common to every key in that subtree) -- this doesn't help with lookups
* at all (unused in == match, could be reconstructed at no cost in <=
* after first dive) but simplifies inserts and removes. If we ever want
* that piece of memory it's easy to trim it down.
*/
/*
* CONCURRENCY ISSUES
*
* Reads are completely lock-free sync-free, but only almost wait-free:
* if for some reason a read thread gets pathologically stalled, it will
* notice the data being stale and restart the work. In usual cases,
* the structure having been modified does _not_ cause a restart.
*
* Writes could be easily made lock-free as well (with only a cmpxchg
* sync), but this leads to problems with removes. A possible solution
* would be doing removes by overwriting by NULL w/o freeing -- yet this
* would lead to the structure growing without bounds. Complex per-node
* locks would increase concurrency but they slow down individual writes
* enough that in practice a simple global write lock works faster.
*
* Removes are the only operation that can break reads. The structure
* can do local RCU well -- the problem being knowing when it's safe to
* free. Any synchronization with reads would kill their speed, thus
* instead we have a remove count. The grace period is DELETED_LIFE,
* after which any read will notice staleness and restart its work.

* The persistent representation of huge memory blocks can be thought

* That list is stored in the chunk headers array where one element
* directly corresponds to one chunk.
*
* U - used, F - free, R - footer, . - empty
* |U| represents a used chunk with a size index of 1, with type
* information (CHUNK_TYPE_USED) stored in the corresponding header
* array element - chunk_headers[chunk_id].
*
* |F...R| represents a free chunk with size index of 5. The empty
* chunk headers have undefined values and shouldn't be used. All
* chunks with size larger than 1 must have a footer in the last
* corresponding header array - chunk_headers[chunk_id - size_idx - 1].
*
* The above representation of chunks will be used to describe the
* way fail-safety is achieved during heap operations.
*
* Allocation of huge memory block with size index 5:
* Initial heap state: |U| <> |F..R| <> |U| <> |F......R|
*
* The only block that matches that size is at very end of the chunks
* list: |F......R|
*
* As the request was for memory block of size 5, and this ones size is
* 7 there's a need to first split the chunk in two.
* 1) The last chunk header of the new allocation is marked as footer
* and the block after that one is marked as free: |F...RF.R|
* This is allowed and has no impact on the heap because this
* modification is into chunk header that is otherwise unused, in
* other words the linked list didn't change.
*
* 2) The size index of the first header is changed from previous value
* of 7 to 5: |F...R||F.R|
* This is a single fail-safe atomic operation and this is the
* first change that is noticeable by the heap operations.
* A single linked list element is split into two new ones.
*
* 3) The allocation process either uses redo log or changes directly
* the chunk header type from free to used: |U...R| <> |F.R|
*
* In a similar fashion the reverse operation, free, is performed:
* Initial heap state: |U| <> |F..R| <> |F| <> |U...R| <> |F.R|
*
* This is the heap after the previous example with the single chunk
* in between changed from used to free.
*
* 1) Determine the neighbors of the memory block which is being
* freed.
*
* 2) Update the footer (if needed) information of the last chunk which
* is the memory block being freed or it's neighbor to the right.
* |F| <> |U...R| <> |F.R << this one|
*
* 3) Update the size index and type of the left-most chunk header.
* And so this: |F << this one| <> |U...R| <> |F.R|
* becomes this: |F.......R|
* The entire chunk header can be updated in a single fail-safe
* atomic operation because it's size is only 64 bytes.
