I guess it does get the main idea across at the front.  We could
include in the "fine print" that the in-memory data can be paged to
disk temporarily when memory is needed for other purposes, and that
it will be saved on clean shutdown for automatic reload when
possible.

As long as the end result is accurate if someone makes it through
the whole thing, I don't think it's a problem to lead with the main
point.  In other words, calling it an in-memory table does capture
the essence of the intent; it is enough if the caveats which come
later cover the exceptions, IMO.  But let's not rename the feature;
this is about marketing presentation.
