Count excuted bytecodes

[Kim Hansen <k-grptens.chp-evb.oe@...>]

I need to be able to determine in a predictable way if a program are
'too big', is it possible to do that with Lua by counting how many
bytecodes a program have executed and stop it after a certain number?

Is there a name for this problem or it's solution, that I could search
for in google, to find out how this have been done before?
