Detailed Description

A simple per-cpu client.

Constructing a CpuLocalClient implicitly creates a session to the given service. Sessions are not closed on object destruction, as it might interfere with modularity (see comments in ~CpuLocalClient). Subclasses of CpuLocalClient (and services) are expected to add another layer to multiplex multiple connections using the same pseudonym (i.e. running in the same PD).
