If you look at the file sqNamedPrimitives.c you will see how
setInterpreter, getModuleName etc are used.
The string returned by getModuleName has to start with the same
characters as the _file name_ of the plugin. You can have any suitable
seeming stuff after that to provide human readable version info. (A
recent change from early implementations)

I don't think any thought was given to having multiple users of the same
plugin. Certainly can't remember it coming up in discussions. I imagine
it might be a problem in some cases; we need to get some info from
various OS experts I guess. I don't think I need to worry for Acorn,
since the plugin is bound into the vm executable address space.

Yes. Try Smalltalk unbindExternalPrimitives and Smalltalk unloadModule:
modulename'. Seems to work on Acorn and linux/x86.
