Comment (by zooko):

 Yes, I've looked at how the auto-retry functionality shown in the stack
 trace (comment:19) works, and it looks like the earlier attempt to publish
 would indeed update the {{{ServerMap}}} object's {{{self.servermap}}} dict
 to have a verinfo returned by the {{{MDMFSlotWriteProxy.get_verinfo}}}. So
 I'm increasingly confident that the fix to #1669 also fixed this bug. The
 next step is to write a unit test that exercises the auto-retry
 functionality with MDMF, which should show the bug present in 1.9.1 and
 absent in 1.9.2a1.

 (Also, by the way, I remain pretty interested in the idea of removing the
 auto-retry functionality completely.)
