Hi, here are some comments about the patch:
- RemoteTraceback, ExceptionWithTraceback, rebuild_exc should be private (i.e.
with a leading underscore)
- in test_traceback, you can use the context manager form of assertRaises
instead of the try..except..else

Hi Claudiu, sorry for the silence.
This output looks great. I'd love to see that go into Python.

Hello. Here's a patch based on c4f92b597074, which adds something similar to
multiprocessing.pool.
The output after the patch is:
concurrent.futures.process.RemoteTraceback:
Traceback (most recent call last):
File
New submission from Ram Rachum:
When you use `concurrent.futures.ProcessPoolExecutor` and an exception is
raised in the created process, it doesn't show you the traceback. This makes
debugging very annoying.
Example file:
#!python
import sys
import concurrent.futures
