We should also apply the attached patch, which corrects a minor issue
with the conditions for flagging transactions that could potentially
make a snapshot unsafe.

There's a small window wherein a transaction is committed but not yet
on the finished list, and we shouldn't flag it as a potential conflict
if so. We can also skip adding a doomed transaction to the list of
possible conflicts because we know it won't commit.

This is not really a related issue, but Kevin and I found it while
looking into this issue, and it was included in the patch we sent out.
