WMs are not RT anything - a correctly written JACK client will interface
with the GUI in a realtime safe way. If the JACK client tries to do GUI

These programs do not even enter into the picture - GUI stuff runs at
normal priority and audio stuff at RT priority so it's impossible for
the GUI to block the audio. Unless the app is broken.
