I've got an Apache2 problem with a registry script that runs another
perl script in a subprocess. The spawn_proc_prog() returns immediately,
though the subprocess is still running, which causes a blocking
situation when I try to read the stdout/err causing the script to hang
indefinitely.

The subprocess script doesn't fork or anything like that, yet
spawn_proc_prog() is not waiting for it to exit.

Any ideas? Need more info? Thanks, folks.

Eric

BTW, using IPC::Run3 -- which I could do since I didn't have to set env
