Thanks for tracking down the problem, Kevin!  The applied patch does indeed 
solve the problems seen with Python's IDLE on 10.9.

As described in Issue19373, the Python project has just issued maintenance 
release candidates, 3.3.3rc1 and 2.7.6rc1, for the current Python 3 and 2 
releases.  The python.org OS X 64-bit binary installers for these releases now 
include a built-in version of Tcl/Tk 8.5 so that users no longer have to 
install third-part Tcl/Tk releases to avoid the critical problems in the 
system Tcl/Tk 8.5 shipped by Apple in recent OS X releases.  The fix arrived 
after the "rc1" installers were created but "rc1_rev1" installers that include 
this fix should be available on the 3.3.3 and 2.7.6 download pages soon.
