I have the same problem on a Toshiba satellite 4070, 366 celeron, 64M
ram, redhat 7.1 and vanilla 2.4.5. Exactly the same bug description.
Totally reproducible.

After a few *hours*.
Then I have (as you said) to do swapoff /dev/hda4 ; swapon -a in order
to free the swap. If I do this, everything is fine... till it fills up
again.
