Yes, I've heard there are some libraries that are smart enough to do
this, if configured so.
However I've also heard of others that use bar-code readers to try and
read the physical label on the media, and that this operation can
sometimes be unreliable and require several retries.
Then there's the question of what happens when your library accomodates
hundreds or thousands, or more media slots.... ;-)
I think the current code, with the bug fixed, is correct for the worst
possible case -- it's only a timeout after all....
