öhm, dat's why i put the (#obj involved) term into my "equation": it 
means "number of objects involved".
this means that it is not a real "recursion depth". (and sometimes it

this is correct.

i was dummified by the "loop" (as in "message loop") and thus was 
immediately thinking of recursion.

well, the speed of the machine does _not_ effect the maximum allowed 
number of loop-iterations. (however, if you are doing audio at the same 
time, you might consider a fast machine and a larger audiobuffer to 
avoid clicks)

i guess the only limitation is the size of the counter.
