I'm having problems with firefox, whenever I run "build.sh" from 
/usr/src which takes a lot of memory, there is about 20-40 MB of stuff 
that gets swapped to disk. While running firefox, I noticed it tends to 
freeze from time to time, once it stops responding there is no choice 
but to run "kill -s KILL" or "kill -9"
I am trying to find the reason behind this, I guess it could be to the 
fact that parts of it get swapped to disk, or the way it interacts with 
my window manager and virtual desktops (I run windowmaker). Also I've 
tried firefox and firefox-gtk2, they both freeze at random times, 
thunderbird-gtk2 is also affected. Has anyone experienced anything like 
this?
