    testGObjectDestructionAccess: Verify that disposed object is monitored
    
    Thanks to the evil hacks we have now we can perform a delayed unref
    without having to rely on pure JS code.
    
    So we can test the case in which a JS-disposed (only) object is later
    finalized by C code.
    
    (cherry-picked from commit a1bbcdae)
