Eliot Miranda uploaded a new version of Collections to project The Trunk:
http://source.squeak.org/trunk/Collections.spur-topa.565.mcz

==================== Summary ====================

Name: Collections.spur-topa.565
Author: eem
Time: 26 June 2014, 5:26:25.563 pm
UUID: 4a254a3f-b4f8-4517-bf98-dbf754764fd4
Ancestors: Collections-topa.565

Collections-topa.565 patched for Spur by SpurBootstrapMonticelloPackagePatcher Cog-eem.160

When a stream is created on a collection, it tries to keep
using that collection instead of copying, even in the case
of mutation of the original collection.

The code removed prevented this.
