in general I agree. It can happen that the output of verious tasks
intermix in interrupt mode.

But: What confuses me in the output is that this intermix happens on a
per character basis. I would expect that it happens with longer chunks
coming from one task, then from the next etc.

Johannes, does your console driver use the termios system for interrupt
output?

wkr,
Thomas.
