They already know who they are when they register themselves. Saving the handle then to avoid finding it later. Not sure if this will increase unnecessary register_dissector functions (instead of using create_dissector_handle in proto_reg_handoff function) when other dissectors copy/paste, but it should make startup time a few microseconds better.
