Depends on why you run out. If your system is active and thus the memory
manager thrashes, swapping pages of RAM from disk, then you need more RAM.
On the other hand, multiuser systems tend to have idle processes lying
around. When out of physical RAM, the kernel takes out the program image,
and writes their data space to disk. This is OK if the swap stays there.
X machines also exhibit this behavior.
