Hmm. I just did some tracing by using Python's trace hooks (neat
trick, although it does produce a lot of output...) It stops in
hammie.py at line 130, which is in DBDict.__setitem__ doing
self.hash[key] = v. That's mildly worrying, as it sort of implies that
the lockup is in the DBM C extension. (If any more Python code was
being called, I'd expect to see trace output).

Any DBM experts in the house?


PS The tracing code I used was as follows. It's quite a neat trick, as
   it doesn't need any changes to the source at all - and by playing
   with the trace hook, you can even dump local variable values if you
   need to...

import sys

def tracer(frame, event, arg):
    if event == 'call':
        return tracer
    if event == 'line':
        print frame.f_code.co_filename, frame.f_lineno
        return tracer

sys.argv = ["pop3proxy.py", "-d", "-l", "8110", "localhost"]
