[PD-dev] allow only one instance of external object

[best boy]

hi
yes, it's for an external i'm writing.
i tried the global counter variable thing you recommended and it works, except for
when the first instance is duplicated, or copy/pasted in a patcher. this crashes pd.

do you, or anyone else, know of a working example of the global counter variable thing?

thanks
olli
