Another interesting approach might be to see whether we can make observers never trigger a release of themselves while being notified.  That might be somewhat difficult, though....

One solution would be to break XPCOM rules and force observers that could potentially release themselves to hold a kungFuDeathGrip on themselves.

We should also avoid calling any dummy mutation observer methods, is just possible.
