Yes, I agree that the argument is only performance (which was one
reason I was trying to avoid a OS timer thread). I am using this hook on
lua threads which have their own environment. The overhead of the
hook would appear to be in the order of >5% . And yes
the table lookups are not so bad in comparison. The Mike Pall
hook count scheme works OK.
There is the strong possibility that I may have originally asked
the wrong question.Restating my problem :
I am executing user code in Lua threads and I seek a low
overhead means of terminating user tasks that exceed
a predefined time limit.
thanks

Setting a hook already has a big impact on performance. Does it make a
significant difference an extra access to the registry inside the hook?
