[issue8296] multiprocessing.Pool hangs when issuing KeyboardInterrupt

[Andrey Vlasovskikh]

Here is a patch that fixes this problem. Basically, it catches all the BaseExceptions that could happen during: a) getting a task from the `inqueue`, b) calling a user function, c) putting a task into the `outqueue`. The exception handler puts the exception to the `outqueue`.

It can be cleanly applied on top of revision 78790.
