The CompiledRouter is not pickle-able because the default responder uses function within functions. As a result, the CompiledRouter cannot be shared between processes using IPC mechanisms, which utilize pickles internally. Replace the function within functions with partials of module level functions so that the CompiledRouter can be pickled. Also, change the traverse method to use the function wrapped by the partial to preserve existing functionality.
