Believe me, it can definitely page to swap. I've used a alot more than that
on occasion. I just now purposely used a bunch of memory on my 2.0.30 SMP
system:
roadrunner:~$ free
total used free shared buffers cached
Mem: 126896 125816 1080 42512 236 15860
-/+ buffers/cache: 109720 17176
Swap: 196596 37928 158668
Then I decided to really thrash it (xv's visual schnauzer displaying
thousands of images works quite nicely for that) and saw:
roadrunner:~$ free
total used free shared buffers cached
Mem: 126896 125240 1656 27724 152 10292
-/+ buffers/cache: 114796 12100
Swap: 196596 165056 31540
Yes, I think it can page to swap quite nicely... :-)
Incidentally, just to make things interesting, the above numbers were
generated using mostly swap files (3 64MB files), not swap partitions.
