Re: How to check if a thread is alive?

Hi Liz,

The main thread spawned many other threads (worker thread). If I join(0ed
any of them, it will cause the main to wait for the worker thread to exit.

It seems to me it is a bug in ithread. If a thread dies, then
ithread->list() should not list it as an alive thread.

perl ithread tutorial & ithread doc clearly state that:

http://www.perldoc.com/perl5.8.0/pod/perlthrtut.html
threads->list returns a list of thread objects, one for each thread that's
currently running and not detached. Handy for a number of things, including
cleaning up at the end of your program:

    # Loop through all the threads
    foreach $thr (threads->list) {
        # Don't join the main thread or ourselves
        if ($thr->tid && !threads::equal($thr, threads->self)) {
            $thr->join;
        }
    }
