----------------------------------+----------------------------
Unter certain conditions cysignal tests fail (building with
`SAGE_CHECK=yes`). This is on the buildbot so directories are the same as
always. Possibly triggered by a full rebuild:
{{{

python -m doctest src/cysignals/*.pyx
cd example && python setup.py build
sys:1: RuntimeWarning: not adding directory '' to sys.path since it's
writable by an untrusted group.
Untrusted users could put files in this directory which might then be
imported by your Python code. As a general precaution from similar
exploits, you should not execute Python code from this directory
Compiling cysignals_example.pyx because it changed.

PS: as always the cysignals.log is useless since it has many different
compilations mashed together and there is no indication where it happened
the first time.
