:-) Looks good! :-) (svn Rev 5047)

At least my standard three job test runs well. All jobs are using the
already loaded tapes.

I also tried some combination of jobs (some with loaded tapes, some have
to load tapes) and had no errors.

Well done!

As this is true for *backup* it doesn't work for reading tapes. Restore
and verify jobs still use the first available drive and not the one
where the tape is already mounted.

I consider this a minor problem. The normal case will be concurrent
running daily incremental jobs where the tape stays in the drive and
will be reused the next day. So when starting this jobs they now reuse
their tape _and_ drive. At least, this is true for me.
If the job needs another tape it is most like because the tape is full
or has errors so the job will need a "fresh" (purged) tape which most
likely has not been used for a long time and therefor it is very
unlikely that the tape is still loaded.
