Util-Timeout (0.01)

A wrapper around Perl's alarm()/$SIG{ALRM}, so it has the same limitations, e.g. you cannot use this to properly timeout external programs started by system()/backtick. For the latter, you might want to try IPC::Cmd (run() or run_forked()), or some simpler interface for it like System::Timeout.
