RS485/LogisticsPipes — pull request #565 by AartBluestoke (2013-02-26 03:08:21+00:00)
Title: various new features:

69 commits, +1900 -900 lines of code.
crafting/providing load balance - pipes without backlog are preferred.
send balancing - senders(qsorts, extractors) will not strongly over-stuff inventories any more.

Mod-sink is now a the lowest priority except for default.
this means that you can terminate stuff before it gets to the mod-sink, and bees will be analyzed over a forestry or extra-bees mod-sink.

Compatability fixes against git-bc and gregtech (backwards comparable),

Further significant cpu improvements, especially to the crafting tree (thanks ArtForz), or handling stacks in inventories.
For best performance use both this LP and the git BC, or a version

BugFixes:
several cases of concurrentModificatoin, or NPE when threaded chunk-ticks are enabled
breaking a pipe now aborts outstanding requests at that pipe.
qsort behaves a bit better.
Items bouncing off full inventories behave much better.
