Since the only thing I know about the multiprocessing internals is what I just read in the source code trying to debug my imap_unordered call, I'll add the following example, not knowing whether this is already covered by everything you have until now.

import multiprocessing.pool

def gen():
    raise Exception('generator exception')
    yield 1
    yield 2

for i in range(3):
    with multiprocessing.pool.ThreadPool(3) as pool:
            print(list(pool.imap_unordered(lambda x: x*2, gen())))
        except Exception as e:

This only prints 'generator exception' once for the first iteration. For the following iterations imap_unordered returns an empty list. This is the case for both Pool and ThreadPool.
