more or less fixes #4 along with changeset e07b15140498

note that i don't understand why the twisted plugin went
through the "wrapper" function.  seems to work just
fine for me without it.  also added the "True"
return value which indicates we handled the call.
however, the plugin hook will need some refinments.
see XXXs.
