It is not crucial for it to be a separate partition. Apple, for

This is common to ALL versions of Unix, as far as I know.
Personally, I have ALWAYS used a separate partition, and I was
gratified to find that I never encountered any of the strange problems
reported by people who left OS-X in its default configuration.
As to the question of whether you need a swap partition at all, given
that you have a lot of memory, obviously you could use a RAM disk for
the purpose. Whether it would be faster is problematical. I seem to
remember somebody tried it - on NetBSD I think - and it didn't speed
things up noticably.
There are many versions of Unix that have an "embedded" configuration,
in which there is often no disk drive. I don't know whether they use a
RAM disk or just do without.
