Comment (by SimonKing):
I did make ptest with a highly patched debug version of sage-5.7.beta2.
Hence, I have the dependencies of #13864 and additionally #9107, #12951,
#13916. #12313, #14058 and #13370 applied.
In the parallel test, I got two timeouts, namely in
devel/sage/doc/en/bordeaux_2008/birds_other.rst and
devel/sage/sage/interfaces/maxima.py. Running the former individually is
long, but fine:
{{{
sage -t -force_lib "devel/sage/doc/en/bordeaux_2008/birds_other.rst"
[339.8 s]
----------------------------------------------------------------------
All tests passed!
Total time for all tests: 339.9 seconds
}}}
However, the maxima test is suspicious. I ran it twice individually. The
first time I got an evil error:
{{{
sage -t -force_lib "devel/sage/sage/interfaces/maxima.py"

Is the error something we should worry about? Or is that likely to be the
effect of a neutrino hitting my laptop?
