And very well, too.

You can prompt it to move pages back into RAM if you start using a swapped-
out process again - say, for example, a quiescent word processor had been
swapped out, you could get it back by raising it and starting to type.

But as Kirk said, there really is no need. It's one of the kernel's many
jobs, and I'm inclined to leave it get on with it!
