Ram-disk? ... Unix?

I'm sorry.  I've only been playing on Unix since about 1983, a short
timer, and *do not* claim to be a guru, but I  have never heard of
such a thing as "ram-disk" mentioned in the same breath as Unix.

I know there are a few new things out there, but this one does not
make any sense to me.  Unix does a lot of things with available ram
and stacks up a lot of disk I/O in memory, but ... .

Did we mistype DOS?

Shared memory might be applied to the original problem but at the
expense of a *lot* of work and rewrite.
