PoCo::Child

[Mike Schroeder]

The PoCo::Child examples all use "ls" as the child program.  This is 
fine for showing how to work with a child that wants some command line 
arguments to generate STDOUT, but I need a solution that lets me write 
to STDIN and respond to STDOUT.  So I reworked the example to use "nl" 
to accept some $c->write() commands and add a line number -- with a 
little tweaking (had to use conduit => 'pty' instead of pipe), this 
works quite well. 

However, I'm not sure how to get rid of the thing!  When I am done 
sending info to the STDIN, I send a $c->quit(), (and checking the 
process list the process is indeed gone), but something seems to be 
hanging on -- POE won't wrap up and clean up after itself -- it just 
hangs.  I tried using PoCo::DebugShell, but PoCo::DebugShell and  
PoCo::Child seem to fight over STDOUT:

       Can't locate object method "OPEN" via package 
"POE::Component::DebugShell::Output" (perhaps you forgot to load 
"POE::Component::DebugShell::Output"?) at 
/usr/lib/perl5/site_perl/5.6.1/POE/Wheel/Run.pm line 379.

Any suggestions on where to go next?
