test_try_finally_raise fails on ubuntu-trusty with sage installed python 3.9 #155

On older systems the test test_try_finally_signal fails:

The failing systems are those that have Sage install its own python. This might be the cause for the problem, I will see if I can figure it out.

For some reason the exception is not registered properly. The execution of the doctester is interrupted, but there is no exception set (and there #156 also doesn't reveal anything new).

I will see if the shebang line has anything to do with it (in src/scripts/cysignals-CSI):

#!/usr/bin/env python3

Perhaps the most revealing error message is
