in thread Can I have a Perl script, initiated from a browser, fork itself, and not wait for the child to end?

Someone gave name the answer over at:

In general you must detach the child process from its parent to allow the parent to exit cleanly -- otherwise the parent can't assume that it won't need to handle more input/output.

} elsif ($pid == 0) { close STDIN; close STDERR; close STDOUT; # or redirect do_long_running_task(); exit;

In your example, the child process is making print statements until it exits. Where do those prints go if the parent process has been killed and closed its I/O handles?
