Or until the operator deactivates and reactivates swap (using
the swapoff / swapon programs), which would lead to anything
still in swap being "synced" with RAM as long as there is enough
capacity to hold them. THis is of course a heavy interference
with how the OS manages memory, and often not a good idea. ;-)
