For my part, I don't know.  A search on bugs.python.org does turn up this
entry, which looks like it might be related:

   http://bugs.python.org/issue834461

I don't know that this explains the empty results from d.get(), but it may
explain the deadlock mentioned in my last message, as the concurrent reader
threads do use cursors.
