That was not what I ment, if you have /tmp comming from disk, it takes disk
space, and on your system you may also have some swap space, which is a
seperate area, if however you use tmpfs you only allocating one lot of
temporary space from the disk not two, also if you have swap on more than
one drive that can be shared onto the tmp area as well.

Clearly there are other times you might what to use tmpfs, and definately
not have swap space, for example if you have a compact flash based drive.
