If we want the tests to fail in this situation, then they should fail reliably,
rather than accidentally pass in a full run as they do now (unless you use
-Werror).  The blackbox test cases should tweak the warnings module
appropriately to make sure that deprecation warnings are always emitted.
Perhaps this is what you meant?

Also, if I'm a developer with an older version of paramiko and Python 2.5, I
think those failures would be a nuisance rather than useful.  Perhaps we need a
flag to selftest to relax the warnings checks, in addition to being strict by
default?
