well, you could just foreground ("fg") the Pd-process after jack_connect
did its job.

however, i think the proper way is to have a separate process running
that auto-connects Pd, e.g. qjackctl with it's patchbay feature.
there are others around as well (google for jack session management).

i'm *firmly* opposed to bloating the Pd core to add jack session
management to "within Pd".
