Nova [0] and Ingen [1] figured this out. along with countless other DAWs and media engines

incidentally theyre all written in C++ rather than C, properly-threaded, use high quality 3rd party libraries throughout, and written by hackers rather than mathemusicians.

Ingen also has a notion of polyphony at multiple levels, such as plugin or subpatch, transparent to any machinations in the subpatch or plugin to fake native polyphony via preallocation and routing schemes.

or if asterisk can talk to jack, sprouting a new PD per-call seems the most plausible, in terms of using PD rather than libingen/nova (ie, not fighting for polyphony or dynamically sprouting jack ports from an existing instance)
