Make speculative accept() faster for the common case
Only do speculative accept on the previous ready set of
listeners. This makes it less CPU-intensive to have per-process
debug listeners configured.
Unfortunately, this makes non-primary listeners unable to accept
connections if the server is under extremely heavy load and
speculative accept() on the previous listener is always
succeeding and hogging the process. Fortunately, this is an
uncommon case.
