100-200 tabs in Firefox? I don't really think Firefox was designed for that.

You're probably right, but since I keep Firefox open for weeks with session recovery enabled, it's quite easy to build up to that. It's also a good way to stress a Linux system, and I have similar tab counts on Windows 7 which doesn't exhibit this intermittent system-wide pause/freeze behaviour (as long as I don't let it page too much).
I'm experimenting with a very small swapfile on Linux (512MB) etc but that hasn't solved this.

Don't worry, you don't need 200 tabs in Firefox to get this behavior. I get it all the time by just running a few more apps than (apparently) the kernel with this hardware can handle. Often - memory at 50%, cpu low, but IO spikes up and typing an email is going back to the '80s with having to wait +5 sec for each character to appear. Embarasing, considering I have little if anything running that requires real resources or IO (mail, chat, feedreader, few browser windows, text editor, filemanager, calendar - that's it).
