Although it's hard to tell because IDK how to make earlier versions work.

  transaction until we can sort out some recent breakage.

- Need to handle exception instances embedded within others.

  I dealt with this in msgpack using a "default" option (essentially a
  msgpack/json form of reduce).

  For pickle, we're still creating instance pickles in this case. :/

- Use a python-msgpack option to produce tuples rather than
  lists.  The ZEO protocol uses tuples far more often than lists.

  This really mostly or entirely affects tests.

  Removed workarounds for some test code that expected tuples and
  added some for test code that expects lists. :)

Avoid waiting on futures using timeouts -> major performance win on Python 2

When data are loaded, we notify waiting code before updating the cache.

This can confuse white-box tests that make assertions about the client
cache after a load, because the cache change may or may not have been
made yet.

By making an unimportant assertion less restrictive.
