Please consider making a helper function.

What about a backingStoreAsBytes() method?  Seems this is a lot of code to copy/paste.

Maybe I should call it CFDataGetMutableBytePtr.  :)

These tests were failing both before and after this patch.  They blinked "pass" on the run before this one, so they got blamed on this patch, as far as I can tell.
