I use something like this in the nanothreads module.

http://metaplay.dyndns.org:8081/svn/fibranet/fibranet/nanothreads.py

This feature is implemented in the Fibra class, in the end and kill
methods. It is used to stop an iterator from parts of the code which
are not part of the loop that is actually iterating the iterator.

This usage is specific to situations where generators are being used
as cooperative threads.
