Knowing next to nothing about the internals of Cocoa Tk, I'm still wondering 
about the significance, if any, of:

1. a universal (x86_64, i386) build of, say, Tk 8.5.15 exhibits the failures 
when run as x86_64 but seems to work OK forced to run in 32-bit mode (i386)

2. the Apple-supplied version of Aqua Tk 8.5.9 in 10.9, apparently built from 
the old DAS sources, appears to work OK in either x64_64 or i386 mode
