I think locking around hint-bit-setting is likely to be unworkable from
a performance standpoint. I also wonder whether it might not result in
deadlocks.
Also, as far as I can see this patch usurps the page version field,
which I find unacceptably short-sighted. Do you really think this is
the last page layout change we'll ever make?
