[New-bugs-announce] [issue24837] await process.wait() does not work with a new_event_loop

[Chetan Reddy]

New submission from Chetan Reddy:

Attached test.py hangs with the following output when run with PYTHONASYNCIODEBUG1= and -Wdefault.

DEBUG:asyncio:Using selector: EpollSelector
DEBUG:asyncio:run shell command 'sleep 2'
DEBUG:asyncio:process 'sleep 2' created: pid 13801
INFO:asyncio:run shell command 'sleep 2': <_UnixSubprocessTransport pid=13801 running>

After i Ctrl-C it, i see the following traceback (paths edited)
