Details | Diff | Splinter Review 
Due to the fix checked in for bug 34871, timers no longer fire accuratly.  This
is partially due to an PRUint32 overflow and partially due to us no longer
resetting timers time-to-fire, so "NOW" is always greater than when the timer
was supposed to fire, so it fires every time the timer queue gets processed
(every 10ms).  We also were not firing with ms accuracy, but instead rounded to
the nearest second.

things that the user might notice:
* the caret in text fields blinking 100 times/sec
* pages with dhtml using timers are horifically slow.  (see test13 or bug 12761)

Seems like a good bug to fix for beta, but not sure why it's dogfood, based on
the symptoms described.
