Bug description:
  Certain databases support two-phase commit. Here's the proposed API:

  store.prepare()
  ...
  store.commit_prepared()

  The implementation of these methods should indirect through the
  backends, perhaps with something like self._connection.prepare() and
  self._connection.commit_prepared().

  If a database backend doesn't support two-phase commit, these methods
  should raise some sort of well-defined "Unsupported" exception.
