Summary: No it doesn't have to be mounted like that.
#2: One suggestion was that it is probably bad to leave it at the default
as it can cause a DoS attack by simply using up all space on /tmp/. This
is a good point, an if you read my NOTE below, you will see why....
#3: Most of the recommendations suggested to leave it on swap for
performance reasons, but to limit the amount of space usable by /tmp.
*** NOTE*** : We have an Oracle server with approx 8GB RAM which had two
kernel panics in the last 60 days. First time there wasn't enough info in
the crash-dump, and sun increased the file space for dumps (or something
to taht effect). The second dump pointed to the fact that a large file
had eaten up all space on /tmp/ (i.e. all swap) and caused the kernel to
panic... which led me to ask this question.

Thank you very much all!
