2.4.1-ac$x and timer oddities

The machine boots and runs for some time without problems, but then
something makes the clock *very* jittery:

* xscreensaver kicks in after almost no time (even betwixt quick
   keystrokes and in the middle of mouse movement), and the password prompt
   timer zips down to nothing post haste
* neworking apps gets a time-out on almost all connections (netscape, ftp, etc)
* It can take quite a while for focus to change after moving the mouse
* The machine will hang (hard - CAD or SYSREQ B do nothing) after a
   variable amount of time (>8 hours)

I think this may've even started at 2.4.0, but seems to have gotten
worse recently.
