[New-bugs-announce] [issue7707] multiprocess.Queue operations during import can lead to deadlocks

[Alon Zakai]

New submission from Alon Zakai <thoughtcube at gmail.com>:

Creating a multiprocessing.Queue and operating on it while being imported can lead to a deadlock.

The attached file will work if run directly (python test.py) but will hang if imported from the interpreter (import test).

Additional comments are in the file.
