There has been an issue on some systems (Linux, it seems) where
POE::Wheel::Run doesn't emit a CloseEvent for children behind a pty or
pty-pipe conduit. Philip Gwyn provided test cases for this, and we
were able to make a fix. POE's repository has it now, and you can get
a copy to try by running:
svn co https://poe.svn.sourceforge.net/svnroot/poe/trunk/poe poe
There's a caveat. The timing between SIGCHLD delivery and EOF from a
child process may have changed. It may even vary. Do any operating
systems even guarantee an order?
If you suspect you have a program that relies on SIGCHLD or CloseEvent
coming first, please check out and test a copy of POE as soon as
possible.
For those whose code breaks, it may be more reliable after revision
2617 to trigger cleanup on CloseEvent rather than SIGCHLD. Programs
will still need to register sig_child() watchers to reap child
processes, though.
