Nit: this doesn't need to be in the try, right? In fact, maybe it makes the most sense right after we do the options parsing? In theory, the other code (e.g. the Host constructor) could log stuff.

I've committed r136474, a simple temporary fix that checks that the exception handled here is not a SystemExit exception. We can address the problem proper when USA wakes up.

whoops. I knew I was going to mess up at least one branch of this somewhere, since of course this is the 5 lines of code I don't have tests for ...

This probably should've been:

try:
  return_code = main()
except KeyboardInterrupt:
  return_code = INTERRUPTED_EXIT_STATUS
except:
  return_code = EXCEPTIONAL_EXIT_STATUS
sys.exit(return_code)

as in the prior version. Thanks for patching this in the meantime!
