When I jump with gdb into clean_stop.py while it hangs:
(gdb) where
#0 0x00007f586bada827 in futex_abstimed_wait_cancelable (private=0,
abstime=0x0, expected=0, futex_word=0x7f5864000c10) at

#7 0x00000000005372f4 in PyEval_EvalFrameEx ()
#8 0x0000000000540199 in ?? ()
And I can confirm that with Debian it does not hang.
Does anyone have an idea what the reason could be?
