Greg created a new API on SBProcess to get an ID that is guaranteed to be unique even in situations where underlying platforms would actually duplicate or hardcode PIDs

The Python data formatters use a per-process cache that was previously keying off the PID. Moving that to be based on this new notion of unique ID.
