OK, so it's not a bug?  It seems unreasonable to block docks from
getting the keyboard focus.  Why does XMonad do it and others don't?

Looking at the docs for XMonad.Hooks.ManageHelpers didn't help me much
(I don't know the XMonad internals and configuration well at all).
Could you provide an example of how I can do this for an Emacs frame
specifically (as created by my example)?

Thanks
