    Revert "object: reset the keep alive flag on wrapper when object is disposed"
    
    This reverts commit 81225d067160a6850eb513ef44b393aeb24ac3ea.
    It was an optional suggestion from me on the original patchset, that I
    thought would let the JS wrappers for finalized objects get garbage
    collected earlier. But it doesn't work as intended, so we can just drop
    it.
    
    Closes #33.
