I suspect it's tunderbird (version 2.0.0.6 (20071101)) and not the system.

I admit I wasn't quite precise when saying Im using *all the same*
apps. I realized this morning that after upgrading, I installed the
above version of binary thunderbird package. The phenomenon is well
reproducable: when Im running my normal set of apps, nothing happens.
Then I start thunderbird, start downloading messages, and swap space
hits the ceiling. Then the system kills off thunderbird. I can even
start thunderbird alone and have the same effect.

So I wonder if that's the same that you're seeing on your two machines?
