another interesting observation:
LuaJIT impact:
noop : 816%
c : 166%
generated: 392%
recursive: 320%
unpack : 158%
both 'generated' and 'recursive' spend most of the time calling
functions and shuffling values in the stack, and get a 3-4 times boost
by LuaJIT. 'c' and 'unpack' OTOH, spend time in non-vm tasks (your C
function and allocation, respectively), and get ony 1.5x speedup.
