The latter (sp!) is essential for other purposes too.

My principle system is a computer with 256 MB of RAM and about 60 GB
of disk.  If I want to do a computation that requires more than 256 MB
of memory, then I'm pretty happy that my system is able to go and use
some of that disk to be able to complete the computation.

Now, it's ludicrous to me that my system forces me to decide ahead of
time which space is for "files" and which is for "backing
store"--these are all simply data objects--but that's a defect caused
by the conventional notion of "filesystem".  That diatribe for another
day.
