The Trunk: Collections-ul.389.mcz

Levente Uzonyi uploaded a new version of Collections to project The Trunk:
http://source.squeak.org/trunk/Collections-ul.389.mcz

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

Name: Collections-ul.389
Author: ul
Time: 15 October 2010, 8:48:17.954 am
UUID: 406e4bb6-951e-1543-80b3-2f0a524cf6bc
Ancestors: Collections-ul.388

- don't wake up all waiting processes when an item is added to SharedQueue2
- avoid double negation and an extra block creation by using #waitWhile: instead of #waitUntil:
- fixed SharedQueue2 >> #removeAll (items is not a stream)
