    I don't see what Objective-C runtime has to do with your problem. Your problem is related to a) dynamic linker, b) application that doesn't unload a plugin once it doesn't need it anymore.
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.

    obj-c keeps various references to dll trying to unload within app causes the app to crash... so it has to remain loaded...it has been reported to apple

    Are you using Objective C?
