What about if you don't have any disk nor any rw filesystems?  Not unusual
in imbedded applications.  The only way to get around it now apparently is
to set up a ram disk and swap to that -- hardly effecient or useful
(except in the case where some RAM is slower).

A typical UNIX workstation or server should always have swap -- there are
always some gettys or something that might as well be swapped out to make
room for more disk cache.  There are applications, however, where swap
is just not an option.
