Comment 0 for bug 366341

I was using FF (of course, with some apps run in background, but actually they were only waiting), when suddenly performance dropped down, I saw 'hard disk usage' light flashing permanently. I even couldn't log in from terminal (tty1) -- so terrible performance it was.
So I did hard-reset and then searched for files have being modified about that time (unfortunately, I cannot determine the moment of actual start -- however, I concluded it from amount of files, if system hangs, less files are been modified, right?).
Output is in attachment.
