Just fine, so long as you've got enough RAM so that everything fits.
Most users of /tmp don't require much space, just very quick access
to small temporary files.
If you plan to put hundreds of MB into /tmp, and your system working
set is similiarly large, then it behooves you to either have 512+ MB
of RAM, or to set up swap space as needed.

It's an environment variable that many programs pay attention to, in
order to decide where to put temporary files. It defaults to /tmp if
not set, generally.
