PHP-FPM and too many requests (lemmy.world)

I noticed that if you have too few pm_children set then some requests hang until timeout. This surprised me - I'd expect an immediate error, but it's more like a tarpit! For ages I was thinking my server was not performant, then I noticed via top that it wasn't doing or waiting while the browser was.

I have two questions:

If you have pm_max_children=1 and you occupy that and submit another request, what actually happens? (I'm proxying through nginx.) HTTP doesn't have a "40_ Come back later".
(if life deals you lemons...) if you can generate a tarpit that doesn't use server resources, this could be quite useful to know about too!

It doesn't forget requests, but NGINX will drop them after it times out if it takes too long.
