added some logging.

we now do an introspection lookup explicitly in math bench on child init

we build and tear down a connection in the unix:server configure hook so
that an applications 'initialize' method can do remote requests

inbound now only opens the socket after receiving data so that a restart
of a unix server won't require a restart of its companion listener process
