Hello Everyone
As I type I am compiling kdepim from Trunk.  The exact spot that it has hung at 
is as follows: [ 57%] Building CXX object 
kmail/CMakeFiles/kmailprivate.dir/globalsettings_base.o

It has been hanging there for about seven minutes.  At 6:32am, the memory colums 
in ksysguard were as follows:
Virtual Size	Memory	Shared Memory
545.2 M		426.3 M	6.4 M

At 6:39am:
Virtual Size	Memory	Shared Memory
573.5 M		454.6 M	6.4 M

At 6:47am:
Virtual Size	Memory	Shared Memory
639.4 M		520.4 M	6.4 M

On a slightly new angle, until I upgraded to Fedora 12, this system has been 
absolutley solid for me.  Since I upgraded to Fedora 12, and ONLY when one of 
these cc1plus processes is hanging while I am attempting to compile KDE from 
Trunk, I have seen my system spontaneously log out.  Nothing apparent in the 
error logs, and I ran memtest for about 4 to 5 hours with no errors.  But that 
may not even be relevant here...

I'm just going to let cc1plus continue to take up memory for a while, and I will 
get back to you later with what it has grown up to...

Oh well, one more time:
At 6:55am:
Virtual Size	Memory
688.6 M		569.7 M
