[...] The SIGCHLD is probably arriving before the child's STDOUT is fully delivered. The two ErrorEvents are probably for STDERR first (since there's nothing to buffer) and STDOUT later. Rather than make people deal with SIGCHLD or counting ErrorEvents, the Wheel should probably emit some sort of "hey, the child is done" event when the child finishes up. I'm experimenting with rt to track simpler requests. This request is at: http://rt.cpan.org/Ticket/Display.html?id=88 More complex requests, like "do the object layer already" are on the web site until designs can be hashed out. http://poe.perl.org/?POE_Design -- Rocco Caputo / [EMAIL PROTECTED] / poe.perl.org / poe.sourceforge.net
