Glad you like it!

Yes I should make the fact that it uses $SIG{ALRM} explicit in the documentation. However note that TimeLimit always uses local $SIG{ALRM} which means that it gets reset to its previous value when it goes out of scope.

The answer to Net::Ping of course is that it should use TimeLimit too if it uses alarm(), or if you have some code that you think might be using alarm() &or $SIG{ALRM} and not resetting it then bracket it in a time_limit { } block and that will reset the alarm() & $SIG{ALRM} properly.

Ideally I should submit TimeLimit so CPAN so everyone who uses alarm() anywhere should use it instead!
