yep, you are right, that's what happened. The livecd mounted the swap 
partitions of all my drives.

I just realised what happened. I started a copy between two external 
hard drives, using dolphin. The copy involved several tens of GB, mostly 
small text files. The process was in the preparation phase, so actual 
copying had not commenced yet, when suddenly I've noticed the activity 
on my internal drives (which were not mounted). I stopped the copy 
process, but the activity continued, until the system became totally 
unresponsive and had to reboot.

I'm guessing dolphin chokes when trying to transfer lots of small files. 
Starts using lots of ram.

I'm now using good-old-fashion 'cp' and all is good.

sorry for the false alarm :)
