bpo-39812: Remove daemon threads in concurrent.futures (pythonGH-19149)
Remove daemon threads from :mod:`concurrent.futures` by adding an internal `threading._register_atexit()`, which calls registered functions prior to joining all non-daemon threads. This allows for compatibility with subinterpreters, which don't support daemon threads.
