in fact we found that --jiton is slower ... just use --jit and benefit 
from the faster virtual machine (the fact that jitting can slow down 
gets obscured by the fact that the vm is twice as fast); i guess that 
the context lua codebase is too large to benefit from jit and also 
hardly uses jitabble built-in functions (much if that is hardcoded in 
jit) and the amount of calls is too low to trade off jitting and using 
(we don't do number crunching or have applications running for more than 
a few seconds)
