If, on the other hand:

Yes, I figured that would be more effective. Well, I can't alter b)
and c), but I *could* switch to a Lua loop. Will report back once I
know more.
Rules of thumb: write all of it in Lua, use Lua tables
exclusively for data structures, avoid frequent upcalls from C to
Lua, avoid calling "black-box" C functions in tight loops.
Interesting. Thanks,
