It is, unfortunately, harder than it could be to determine how much
memory a given process is really using on a system with dynamic shared
libraries.

I suggest starting with 'top' (hit shift-M to switch to sorting by
memory use - RSS by default I think) or using ps and sorting by RSS.

Possibly, though it's more likely to be lovely leaky programs.

Only by terminating the process(es) that use them. The kernel will swap
unused segments of code out automatically though so it's not a big deal.
