Python testrunners like to swallow output from print statements,
unfortunately. Some also like to swallow pdb breakpoints.
I believe the Right Way to do this sort of debugging in tests is to use
Python's logging framework. But I'm always too lazy to look this up. I
usually end up doing ``logfile = open("/tmp/test.log", "a"); print >>
logfile, "log message"; logfile.close();`` instead, and `tail -f
/tmp/test.log` in another console window while I run my tests.
