you can set 'count hook' after creating Lua state and then
atomically check 'stop now' flag in this hook. it wouldn't be 'immediate
stop' (without sacrificing performance), but it can work fine (and it
works for me). the big plus (i think) that i can see where script was
interrupted (with help of debug traceback). just fine-tune counter
(once per 100 VM commands, once per 1000, etc). i think this can solve
most of the problems.
