If I remove the _needmain stuff in the show() function in the TkAgg backend, then each call to show() blocks on Mac OS X with the TkAgg backend, which (in my understanding) is the desired behavior. I don't know the purpose of _needmain in the show() function, other than to disallow multiple calls to show().
