For this initial testing, I'm running Django directly. In production it will be run behind Apache/mod_wsgi.
Setting sys.coinit_flags = 0 fixes the hang when running Django from a simple command line. This confirms to me that the issue is thread-related. What I'm seeing now is that the hang still occurs when running under the PyCharm debugger, but functions correctly in all other cases (run directly, run under Apache/mod_wsgi). It's no longer a blocking issue for me, but it would still be nice to understand root cause and if anything can be done (in my code or in PyCharm) to make the debugger function correctly. If you guys have any ideas on how to further debug or collect information on what might be hanging, that'd be greatly appreciated.
