There's a builtin debug tracer you can use for cases like this.
Sometimes I take a test like this:

    def test_some_storm_code(self):
        < some setup logic >
        < the Storm-using code I'm curious about >
        < more stuff >

And I use the debug tracer to see what's going on:

    def test_some_storm_code(self):
        < some setup logic >
        from storm.tracer import debug; debug(True)
        try:
            < the Storm-using code I'm curious about >
        finally:
            debug(False)
        < more stuff >

We should probably provide a context manager so that you can use
'with', since it'd involve a touch less typing, but this is handy
nonetheless.

Thanks,
J.
