the default seems to be 1024 on my unstable system.
the test fail with Python3.14 but not with Python3.13.
so this is a difference
I did this on my local machine and it works if I set this limits says to 10000.
picca@page:~$ ulimit -n

If I set this limits to 10000 it works for Python3.14 and Python3.13
I can not run the test in autopkgtest due to this bug
