Once per Squeak after the DLL was successfully loaded, getModuleName() was
called and right before the first pluggable primitive is executed.

Probably once per Squeak - I haven't checked. But that's not the problem -
I confirmed that it was never called - because of the name I returned in
getModuleName().

Really? I hoped that each instance would get its own set of globals...

That would be bad. But this would actually also break all existing Plugins
then as all other also store their VM proxy pointer in a static global
variable.
