Comment (by SimonKing):
Should we add tests in the spirit of this:
{{{
sage: from sage.data_structures.bounded_integer_sequences import
BoundedIntegerSequence
sage: B = BoundedIntegerSequence(4,[1,2,3,2,3,2,3])
sage: while 1:
....: C = B+B
....:

As you can see, the interruption occurs in the correct place already in
the second try.
