I took another look at v2 of my lazy vxid locks patch and realized
that it was pretty flaky in a couple of different ways. Here's a
version that I think is a bit more robust, but considering the extent
of the revisions, it probably needs another round of review from
someone before I commit it.
Any review appreciated; I would prefer not to have to wait until
October to get this committed, since there is quite a bit of follow-on
work that I would like to do as well. FWIW, the performance
characteristics are basically identical to the previous versions,
AFAICT.
