Greg just tipped me off to this thread a few hours ago. I saw your other
work on timeouts which looks good.
I've reworked this feature myself, and its roughly the same thing you
have posted, so I will just add on to this thread. The major change from
my earlier patch is that the logic around setting xmin on the master is
considerably tighter, and correctly uses locking.
Patch attached, no docs yet, but the patch is clear.
I'm looking to commit this in next 24 hours barring objections and/or
test failures.

Probably, but its a small change and will conflict with other work for
now.
