This is fairly unlikely but occasionally comes up on the buildbot:
{{{
sage -t --long src/sage/homology/simplicial_complex.py
**********************************************************************
File "src/sage/homology/simplicial_complex.py", line 2236, in
sage.homology.simplicial_complex.SimplicialComplex.is_cohen_macaulay
Failed example:
S.is_cohen_macaulay(ncpus=3)
Expected:
False
Got:
[Errno 2] No such file or directory:
'/home/buildbot/build/sage/snapperkob/sage_git/dot_sage/temp/snapperkob/10634/dir_n0BDmn/10759.out'
False
}}}
Apparently the code uses @parallel and there was already a race fixed in
#14150.
