Log Message:
Shuffle the pagedaemon algorithm a bit to record the number of
pageouts active and give up only if the pagedaemon could not free
memory and there are no outstanding pageouts.

This should fix the "out of memory" pauses reported by Mihai Chelaru
and Taylor R Campbell.  Tested by copying files to and from an ffs
backed by /dev/wd0 (with and without -o log) using a 1MB rump kernel
memory limit.
