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; } } J.
