Even the perception that it's "slow relative to LuaJIT" is a bit
misguided... LuaJIT offers a very nice speedup for certain types of
operations, but this doesn't always result in the whole program being
much faster... many things, LuaJIT just can't optimize all that well.
[This is especially true if you're trying to be portable; getting the
ultimate speed out of LuaJIT often involves writing LuaJIT code, not Lua
code...]
