When you call JS_InitClass, it creates a prototype object of your class, 
so that object will be finalized too.  It won't be constructed, though 
-- you have to call the constructor yourself, if you need to.

Most class prototypes don't need to be constructed, but that means if 
JSCLASS_HAS_PRIVATE, JS_GetPrivate will return null for such objects, so 
your finalize implementation has to null-check.

You'll have to debug a bit more to say why you see two finalizes other 
than the one for the instance you create explicitly in JS, via new. 
Perhaps you JS_InitClass in two different global objects?
