one workaround is to make a global map<MyClass,int> where int is a dummy
(unfortunately, void is not accepted as an argument of that type-pattern).

This doesn't sound right. Note that there are some things that apply to
objects that are directly global, and don't apply when the global
variables are just pointers. I almost always use the latter because the
former is a pain in the ass. (any static variable counts as global in this
case, because they're essentially a kind of hidden global).

ow. so what can it do in case of segmentation fault or other crash of
Pd?... what happens if you bang a naked [until] while you use your wacom
thing?
