Comment (by SimonKing):
Apart from the strange glibc problem (that is not reported at the end of
the test suite), I get one timeout, namely `sage -t --long -force_lib
devel/sage/sage/crypto/mq/mpolynomialsystem.py`.
Aha! And it turns out that the glibc comes from that test!! Here is what I
get in detail:
{{{

}}}
So, these are very few commands. That should be reproducible (trying it a
bit later).
For reference: The problem does not occur with
