I didn't quite understand the multiprocessing test cases, but attached is a standalone test case that reproduces the problem. The problem only shows up when using ThreadPool.

$ python thread_pool_exception_test.py
Traceback (most recent call last):
  File "thread_pool_exception_test.py", line 7, in <module>
    pool.map(exception, [1])
  File "/opt/local/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/multiprocessing/pool.py", line 255, in map
    return self._map_async(func, iterable, mapstar, chunksize).get()
  File "/opt/local/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/multiprocessing/pool.py", line 594, in get
    raise self._value
TypeError: exceptions must derive from BaseException
