[CM] blocking processes in cm

[Orm Finnendahl]

Hi,

 is there an easy way to define a sequence of processes in cm without
having to determine the length of the process beforehand? As far as I
know, the recommended way to have multiple processes is using a sprout
which schedules the processes in parallel and the timing is done with
the wait which inserts the sprouts at the respective position in the
queue.

My idea would be to have the process block until the subprocess
scheduling is done and then trigger the next iteration of the process
loop with an optional wait parameter.

I'm aware of ways to get this mechanism working outside of cm, but as
I'm teaching cm to my students I would prefer a way with the means of
cm itself.
