Here's a bunch of fixes to improve watch performance when
both Maildirs and NNTP are being watched (possibly on the same
inbox, or if `watchspam' is configured for spam removals).
Wakeups are reduced, and inbox.lock contention is minimized by
using read-only ->over to check for `watchspam' removals.
These affect IMAP, too; but I've been mainly using NNTP.
Eric Wong (11):
watch: limit batch size of NNTP and IMAP workers, too
watchmaildir: use v5.10.1, drop warnings
rename WatchMaildir => Watch
watch: log signal activities to STDERR
watch: avoid unnecessary spawning on spam removals
watch: block signals before fork on non-signalfd/kevent systems
watch: comments and tiny cleanups
ds: avoid excessive queueing when reaping PIDs
watch: use EOFpipe to reduce dwaitpid wakeups
ds: avoid unnecessary timer for waitpid
replace ParentPipe with EOFpipe
