*	SI-8153 Mutation is hard, let's go shopping with an empty list	Rex Kerr	2014-02-12	1	-0/+1
	Changed the implementation of iterator to be more robust to mutation of the underlying ListBuffer. Added a test to make sure bug is gone. Fixed an "unsafe" usage of ListBuffer.iterator in the compiler, and added a comment explaining the (new) policy for iterating over a changing ListBuffer. The compiler now uses a synchronized-wrapped ArrayBuffer instead of ListBuffer, as that makes the (custom) units Iterator more natural to write (and avoids O(n) lookups).
