Thanks for the help. This really gives me a lot of traction on the problem. I'm only running POSIX::_exit($!); if !$pid because it appears that open3 already sends some output to STDERR. I don't see how to stop that and send my own custom error message, short of writing my own open3. But this is fine.

I also still have a check for $@, since I suspect that it would be set if the fork() failed.
