Also - see if there is an 'alarm' pop-up - maybe with lost Z-focus - hiding
under Firefox trying to tell you a site is unreachable after trying for 
't' time...

Suspected on Mac OS X hangs, but 'top' - even with flags, doesn't show 
if it is in
kqread or riding horseback.... (and the F'fox crashes more often than 
Moz as well)

IOW - may not be a DFLY issue at all....
