In my case I get to the point where all Mem + all Swp is full
according to top, and the virt may be 2-3X as large as RAM + SWAP. I
don't really understand how that is managed, but I do tend to have
LOTS of problems when that occurs. The big user is Opera - I may have
up to 150 tabs open in several instances.

Even though there are 100+ tabs open, I have looked a MANY more. Are
these being swapped out to virt space? And if swap is full, where do
they go? Is that what's behind the problem?

Interesting... that does not seem to be large now [but Opera is VERY
small now [after recently crashing].

I use a moderately inexpensive case too, but they're OK. I did get rid
of a free case which was reeeeally difficult to deal with
mechanically. :-)

Thanks for the info...
