assert bitmap equality as binary strings not ints - produces more understandable asertion errors
fix sameKey bug and stash delegate splicer for better debugging
lose a println()
split a loop with a repeated boolean test into two different loops - this loop was responsiible for 70% of splice time when I measured and now it is not :-)
typeInt and multi-method jump table were consuming 10% of splice time when measured - replacement code does not
playing around with hash-map testing - going well
exploratory work on parallelising hash-map splicing - very promising results
initial graph of hash-map splice timings on 16 core cpu - nice !
lose dead  code
some thoughts on parallel impl
