While each git blob request is treated fairly w.r.t other git blob requests, responses triggering thousands of git blob requests can still noticeably increase latency for less-expensive responses. Move large mbox results and the nasty all.mbox endpoint to a low priority queue which only fires once per-event loop iteration. This reduces the response time of short HTTP responses while many gigantic mboxes are being downloaded simultaneously, but still maximizes use of available I/O when there's no inexpensive HTTP responses happening. This only affects PublicInbox::WWW users who use public-inbox-httpd, not generic PSGI servers.
