Is it really of much use for your access method? It's such a crude hack
that I didn't want to encourage people to use it ... it is really just a
stopgap until someone gets around to thinking harder about the actual
access behavior of the existing index AMs.
BTW, what are you working on? I had no idea that anyone was
experimenting with new index methods.
