information lookup

   > If the client happens to be communicating with the active master, it's

the location of the active master.
   
   I'm a little confused. With patches like #812 #830 etc all the running 
masters (active/stand-by) can serve the information needed  by a connection 
registry. For example: stand-by masters keep track of active masters so that 
they can serve the "get active master" request. Client does not need to keep 
retrying until it finds an active master. On top of that we now also have the 
ability to hedge requests across masters (#954). Did I miss something?
