Not quite. Polygraph v4.8.0 makes it easier to use multiple processes on
the same box. Here is a list of the related features:

The plan is for Polygraph v4.9.0 to start those multiple processes
automatically so that you do not have to write a script to do that, but
there is currently no sponsor for that feature.
