Subject: [PATCH] Change direct references to the isa pointer to calls to
 object_getClass().  In discussion with Steve Naroff (before he left Apple) it
 was decided that the isa pointer should be regarded as an implementation
 detail and not part of the language, so direct references to it are
 deprecated (on OS X).  This gives the runtime a bit more freedom to do secret
 isa-swizzling tricks.

I've had these changes sitting in my copy for ages - no idea why they weren't
committed.
