No.  I want to know what the subordinate does when it's promised to
commit and the co-ordinator never responds.  AFAICS the subordinate
is screwed --- it can't commit, and it can't abort, and it can't expect
to make progress indefinitely on other work while it's holding locks
for the not-quite-committed transaction.
