Many thanks for the clarification, Miller.

The challenge I am trying to figure out is a memory leak report that Jonathan shared with me. See:

https://sourceforge.net/tracker/?func=detail&aid=3605235&group_id=55736&atid=478070

Basically deleting and creating the same object (in this case through script as that is obviously quicker than doing it manually) keeps pd (or pd-l2ork in this case) growing in terms of its memory footprint. I was hoping that closing the patch would free that up but it doesn't...

Hence, my little adventure into figuring out why the said call. I am sure there are others as even disabling that call doesn't help much in curbing the growing memory footprint (at least over here).

I don't remember why it's there (and perhaps it's no longer necessary) -
but I suspect it had something to do with a subtle problem when deleting
a GOP whose interior got mad wieh there was no rtext for the owning object.

The rtext eventualy goes away when the window is closed - but perhaps it's
a problem if there's a self-editing patch that creates and deletes
1000s of objects in an open window?

cheers
