Threads probably complicate that too. It's dreadful that serious problems can get transformed into bogus KeyErrors

Yes. Here is a patch attempting to do what I described: http://www.python.org/sf/1009929

It's an extension of the asynchronous exception mecanism used to signal between threads. PyErr_Clear() can send some exceptions to its own thread using this mecanism. (So it is thread-safe.)
