Well, this may half-please you. :-)  It's not set up that way out of the
box.  But at least part of it -- expiry only on space shortage -- can be
done by minor changes to shell files.  People have done it.  We don't
have a "remove list" or anything like that, but you could get much the
same effect by doing iterative expiry, generating expire control files
specifying successively tighter expiry times until you had enough free
space to suit you.  The overhead needn't be very high if it's managed
intelligently.  Again, we don't provide the solution, but I think most
of the tools are there to build your own.
