Erlend E. Aasland  added the comment:

FYI, this buildbot has been green after Victor's git clean adjustment in the 
buildbot repo.

I've been trying to reproduce the test_still_running failure on the buildbot, 
but have not been able to do so deterministically.

On my laptop with 4 physical CPUs (8 threads), I can reproduce 
test_still_running() random failure with:

Mark Shannon  added the comment:

I cannot reproduce this on ubuntu

Ubuntu 20.04.2 LTS
gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0

I've tried these configs:
./configure --with-pydebug
./configure
./configure --enable-optimizations
./configure --enable-optimizations --with-lto


I also tried turning the timeout down to 2 seconds, but the failure doesn't 
look anything like the reported error.

Mark Shannon  added the comment:

And today's price for uninformative error message goes to...
"AssertionError: 'False' != 'True'"

;)


I'm looking into it.
