     * static initializer in the main class), not the VM.  It's done this
     * way so that the handlers can use Android classes with native calls
     * that aren't registered until after the VM is initialized (e.g.
     * logging).  It also allows debugging of DDM handler initialization.

     * The chunk dispatcher will pause until we call registrationComplete(),
     * so that we don't have a race that causes us to drop packets before
     * we finish here.
