Monks,

I'm seeing IPC::Run spawn a child process which runs as expected, but when the child completes and exits, the parent doesn't notice until the timeout has completely elapsed. The child is listed as a zombi by ps(1). I run this: 

$ time perl -MIPC::Run=run,timeout,timer -lwe 'run(["/bin/sleep", 5], 
+timeout(10));'

[download]
and get this: 
0m11.129s (0.100u 0.000s)
11 seconds elapsed because the parent didn't cleanup the child process when it finished.

If I simply change the timeout to 3 seconds, I get the expected behavior of IPC::Run throwing an exception.

I've installed IPC::Run v0.80 with the CPAN shell, with a package I built myself and with a Fedora package I downloaded, as well as a Fedora v0.79 package I downloaded, all give the same result.

I've used IPC::Run before without this problem on the same architecture I have now and can't find the culprit.
