good to know but that didn't help.

I can't tell what it is but apparently it's a timing or order of execution issue at startup in batch-mode:
Delaying the ; pd dsp 1 message by 200ms helps avoiding the "device busy" error.
Same patch loaded in the gui, no problem.  :-\

According to 'top' the cpu load drops from 75% to about 70% with -nogui for a 4k-window.
Just about enough to avoid glitching.
But any system activity brings the sound to a halt for a short moment.

So that was just an ssh-session and Pd running in batch-mode.

At some point I'll go through this and see what can be done:
