Yes, this is a known issue - not a bug, but definitely something that
can be improved.
There has been a discussion about this which I can't find in the list
mail now (so you'll have to search yourself ;-)
I'm rather sure that there will be configuration statements available
to miodify this behaviour some time, but I'm not sure if this in the
queue for the next release.

Sure? I don't think I ever observed this. In fact, I'm pretty sure I
have had to cancel jobs for that exact reason every time I forgot to
load the correct tapes in the autochanger and so a full backups waits
all night and is still running when the next incremental one is started.

Yup... this is one good reason to keep your backups small enough they
can finish in less than 24 hours :-)

You can't, now, I believe.
