This was hiding behind the full-screen game, so the system just locked up. While playing Civilization IV (a large, full-screen game), the system ran out of hard drive space (~50 megs free) and presented the "kill apps now" window. The latter I've experienced (with the swap file enabled) when running out of disk space.

If you disable it, you may not be able to run as many programs at the same time (and the limit is far lower than you'd expect) or you may have issues (like freezing and having to hard-reboot the machine) when you run out of memory. The swap file is there for when your running programs consume more memory than you have physically installed. It is almost always a HORRIBLE, HORRIBLE idea to disable your swap file. That said, this is definitely a case of premature optimization. Swap files can be written to frequently, possibly causing disk fragmentation (as well as file system fragmentation) and, eventually, possibly causing the disk to fail sooner. The reason they disabled the swap file is likely paranoia about SSDs having a maximum number of writes per block.
