I made (unconsciously) a guess that it's a fire-and-forget subprocess,
the simpler case why it would be necessary that it doesn't block the
parent. Seems (from the later followup) I guessed right, but thanks for
bringing that point up for cases when it isn't, I'm admittedly flaky
when it comes to process synchronisation.
