/**
* a service is used to serve one or more requests from an input stream and post results on an output stream.
* when the input sream is closed it is expected to close its output stream.
*
* note that a single service instance may be requested to process incoming requests from multiple input
* streams in parallel.
*
* note also that the service should be resilient to closure of the input and output streams during request
* processing which can happen in resposne to asynchronous dispatch of a shutdown request to the object which
* invoked the service.
