They are *not* similar to in-memory table, in that they are *always*
written to disk. AFAIK that is - or do they actually get spooled in
RAM-only until they get big enough? I'm prettysure they don't.

They *are*, however, pretty similar to global temporary tables. Are
those well known enough to be used for the pitch without mentioning
in-memory tables?
