I'm currently running without any extensions on 64-bit 3.1-0.2.rc2.fc14. 
Yesterday the bandwidth from work to home was constrained, but it is 
back to normal today.  My CPU is a quad-core Opteron and should not be a 
problem in that at the time of the freezes, I was running Firefox and 1 
or 2 Gnome-terminals. I'm going to use this today to see if I have any 
freezes. Running X over IP through an ssh tunnel has its own issues, so 
it really is not a valid test. I did experience a freeze while typing 
the word, 'test' in the last sentence, but as I stated, it is not a 
valid test.

My plan over the next few days is to run 64-bit 3.1 from Rawhide with no 
extensions with ntpd and possibly some other daemons disabled. Another 
possible cause is that it may be trying an IMAP sync to GMAIL.  The two 
tests here is to (1) change the timing, and (2) do offline and only 
manually get mail. After reading some of the posts on the T-Bird list, 
I'm leaning in this direction.
If things go well, then we'll re-enable some of these. I will install 
the 32-bit 3.1 with no extensions and see if that is clean, then install 
enigmail and a few other extensions after testing for a while.

The one common factor is that top shows Thunderbird using 100% CPU.
