After upgrading from 7.3 to 8.1, moused has started drawing 100% CPU
(even when the mouse is not used).  moused -d -f doesn't output anything
suspicious  - in particular, it does not display anything when the mouse
is not moved.

root    10833 100.0  0.1  1732  1100  v0  R+   10:51AM   8:47.62 /usr/sbin/moused -d -F 200 -A 1.5 -a 0.5 -p /dev/cuau0 -t auto -d -f

FWIW, I was using the uart serial driver even on 7.3.  (Maybe this is
also the time to mention that mouse movement got much slower after the
move to uart - that's why the -F -A -a settings are in there.)

Any help would be much appreciated!
