CK Tan and I worked on something similar but the problem we discovered
was self locking. Consider a primary key: we insert a tuple into a
buffer and do not release the exclusive lock. The btree code fetches the
buffer and tries to share lock it, but we've already exclusive locked
it. Oops. The performance improvement, though, makes it worth seeing if
there is a solution.
