Comment (by jdemeyer):
With these patches + the patched sagenb
(https://github.com/sagemath/sagenb/pull/84), I get just one sporadic
failure:
{{{
sage -t --long devel/sage/sage/homology/simplicial_complex.py
**********************************************************************
File "devel/sage/sage/homology/simplicial_complex.py", line 2188, in
sage.homology.simplicial_complex.SimplicialComplex.is_cohen_macaulay
Failed example:
S.is_cohen_macaulay(ncpus=3)
Expected:
False
Got:
Exception OSError: (10, 'No child processes') in <generator object
__call__ at 0x646f1e0> ignored
False
**********************************************************************
}}}
I have not investigated, but I assume it must be some strange interaction
between the `DocTestWorker` processes and the `cohen_macaulay`
subprocesses.
Since `bsd.math` has been down for a while (now it is back up), I haven't
been able to look into the OS X issues.
I guess the only remaining issue is `--gdb` (and `--valgrind`...) support.
