Overview
Rack middleware that cleans up any 'p4' handle added to the environment during processing.
This should always run, even in the face of exceptions. Make sure any middleware configured after this step does NOT swallow exceptions.
This expects that if a temporary workspace was generated, the 'p4_root' variable was also added into the environment. See P4Helpers.
