Yes, it's not perfect.  It is a compromise between occasionally laggy
interactive sessions and entirely abandoning ControlPath, as well as hacking the
command line options to achieve a similar effect.  And it's optional to use.

Some may consider it feature creep; I don't know.  Just sharing for any one else
that may benefit from its use.
