what I mean is, NetBSD ought to throw away cached pages, before commiting
swap space to storing executables/data in use (unlike certain other OSes
which preemptively (or stupidly) put pages in swap, when there's still
plenty of real memory to be worked with).

I'm assuming that it generally makes the right decision about these things,
since it seems to be a competently-designed OS. :)
