         * for the sake of anything that needs to do disambiguation in a
         * common handler with INST_INST.

         * The breakpoint itself is handled over in updateDebugger(),
         * because we need to detect other events (method entry, single
         * step) and report them in the same event packet, and we're not
         * yet handling those through breakpoint instructions.  By the
         * time we get here, the breakpoint has already been handled and
         * the thread resumed.
