[PD] trouble with data structures

[Chuckk Hubbard]

If your score gets too long, though, and you have too many of one
before the other, you can get overflows from this.  Because the action
of checking each scalar is a result of the output of the previous
scalar, one "next" message can start an indefinitely long string of
messages.
I find using a 0 ms delay to work for this; the next string is started
as a new command, or at least that's how it seems.  Anyway, it works
as in the attached patch.

This might not be an issue for you, if you are talking about two
separate structures that exist for each note, IF you sort the score
each time, because then there is never more than a couple of one
before the next instance of the other.  But if you start adding
anything else to your score, like tempo markers, bar lines, or any
sort of automation, you might run into this.
