Comment:
Normally, only pipes created by the `System.Process` library are closed in
child processes, all other FDs are inherited by default. You can request
that all FDs are closed by using the new `close_fds` flag to
`createProcess`; try this replacement for the line containing `runProcess`
in your example:
{{{
forkIO $ createProcess (proc (dir </> pn) ["arg"]){ close_fds=True } >>
forever (threadDelay 100000)
}}}
This behaviour is fairly standard, it's what `popen` on Unix does, and it
also follows the Python library.
