The first thing required to get this to work is a primary key on the reserves
table!  Right now, borrowernumber + biblionumber are being used as the match
point, which precludes multiple holds on a single title.

The patch here is insufficient by itself, and references a system preference
not already in Koha.  Marking as obsolete.

The need for some kind of restriction mechanism still exists; not all libraries
will want patrons to be able to place multiple holds on a material; this could
lead to gaming the system by placing holds on every available copy of a popular
book, for example.  I think a control mechanism that looks at the
items.enumchron field for distinct values would be a way to go; this would let
different vol/issue items, for example, take in multiple holds, but equivalent
copies could still be restricted (unless they were explicitly given distinct
enumchron values)
