in reply to get stdout stderr

I don't know if this is directly related to your issue and I've never worked with IO::CaptureOutput, but I've had difficulty shelling out in the past while capturing output to scalars. Detailed in STDOUT redirects and IPC::Open3, essentially the fileno of my output handles no longer corresponded to 0,1 and 2, and so the linking was lost on system call. The only solution I've found, assuming this is your issue, is rolling my own system call wrapper with pipe and fork, like in Re: How to capture child process output and divert to log4perl. In some cases, depending on some particulars, I've had to explicitly open unused filehandles to hold onto the right filenos until I needed them -- the system doles out filenos by the lowest one available.

Or all this could be off base for your case.

Lady_Aleena was checking #cbstream and saw the big announcement.
[marioroy]: Tie::IxHash can be shared. Also similar modules. I cannot wait to post a solution sharing Tie::File and iterating among workers.
[marioroy]: Lady_Aleena Yes, will post something with all the new features. Parallel with few lines of code.
[marioroy]: Yes, will do for PM. I love PM.
Lady_Aleena ponders a meditation of her own, but it would be on a far far less important topic.
[marioroy]: I'm hoping to have a release in about a week's time.
Discipulus supermario..
marioroy MCE isn't important by any means. Just wanted to complete this task. Hobo needed more love and MCE::Shared as well. It wasn't easy at all.
