I am working on a system on algebra.com where anyone
could define a math solver for a particular kind of
problem. It could be defined either via a custom
markup language (not interesting), or as a perl
script.
These user submitted perl scripts will be executed
inside Safe.pm compartment. I hope that they will be
secure enough.
My question is, is there some way to limit execution
time of a subroutine? I would not want those scripts
to run for more than a second CPU time.
