holding disk/taper semantics?

[Carey Jung]

Could someone please clarify the holding disk/taper semantics?  It appears
that amanda deletes files from the holding disk as they are taped off,
rather than after they are ALL successfully taped off.  We noticed this when
we had a tape problem.  When we put a good tape in and tried to re-flush the
files, they had disappeared from the holding disk.  Watching the behavior
since then seems to confirm this.
