AAAARGHGH! lookdict "isn't allowed" to raise exceptions, so it does a PyErrClear(), goes on to futilely chase the entire dict looking for another match on the hash code, and we've effectively turned a MemoryError into a KeyError.

This suggests to me that the very concept of a function that's not allowed to return errors is dubious, since even just calling another function could provoke a MemoryError.
