In Emacs sticky keys aren't so simple.  The one you give is a fairly
good example.

The keybindings of the form "C-c C-something" are used by the current
mode.  So, C-mode enables "C-c C-c", for example.  The bindings of the
form "C-c something" are for the user to define.  Where the "something"
isn't control, of course.

How is this to work with sticky key?  Does the user have to press ctrl
then c and then ctrl again to switch off the stickiness before pressing
c the second time?  A timeout could also be used, but that brings it's
own problems.
