but why?
if you have this flag, someone (the application) has to take care of not
reusing the signal-vectors. this involves copying the data to somewhere
else.
if there is no such flag and you want to acoid reusing the
signal-vectors, you have to copy the data to somewhere else.

so the "terrible waste of cycles" will always happen, the decision to
make is whether max/msp does it automatically or whether the
pd-developer has to do it by hand.
