reactor: add pid to names for rings and mempools

Browse Source 
This is required for using the event framework
in multi-process mode since they must be unique
across the group of processes..

Currently the stub app calls into the env layer
directly, bypassing the event framework, so this
issue would only be seen with multiple secondary
processes using the app framework.  Some future
changes will change the stub app to use the event
framework which necessitates this change immediately.
