Before this BTree fix, you could store integers in an IxThingy (or
xIThingy) that were too large to fit in a 32-bit C variable. This
would cause the values to overflow and be silently stored incorrectly.
With the fix, a TypeError is raised when an attempt is made to store a
value that is too large.

Whether this fix will adversely affect your application, I don't know.
Hanno seems to think it will. :) Avoiding silently storing values
incorrectly looks all good to me.
