Linux will start swapping programs out to disk which haven't been used in
a while to make more room for filesystem cache.  Even if you have
gigabytes of memory in your machine, if you do a lot of work with large
files which exceed the amount of memory in the machine, the kernel will
start swapping some things out to improve performance.
