The autoexpire system simply runs every few minutes and notices that
space is short on the myth partition.  If it does, it deletes shows
in its order (right now highest autoexpire number, then oldest first)
until space is recovered.

This applies to anything that is eating space, be it new recordings,
or ripping DVDs or whatever else.

The only time this fails is if you copy in stuff so fast that you use
up all spare space before the autoexpire can run.   This is actually
rare (dvd rips and cd-rips are not that fast) and can be fixed
by running it more often. 

This is not related that much to the concept of undo for delete.   This
is the story any time the disk gets full enough to need autoexpire, be
it due to the proposed feature or just because you are not deleting shows
manually fast enough.
