pm.max_requests is similar to MaxRequestsPerChild.

But these are not really things that you'd expext to necessarily
balance on each side of an equation. The moral of this
thread is that you likely had queueing because your HTTP server
accepted more parallel requests then your backend
scripts would accept based on the FPM settings.

But how that pool grows on the backend maybe different from how you
wan it to grow on the frontend -- the cost may be very different,
and the http server might serice requests that don't go to FPM.
