Q: Why yet another .Net 2.0 Blocking Queue implementation?
A: I was looking, back in December 2013, for a Blocking Queue implementation for .Net 2.0 but none that I found were simple or reused existing .Net functionality.

Q: What??
A: I wanted an implementation to (1) encapsulate all the syncronization machinary, (2) extend Queue and (3) reuse Queue.Synchronized.

Q: How is it simple to use?
A: Use it like so:

 using System.Collections;
 using Gh.Os.Concurrent;
 ...
 Queue blockingQueue1 = BlockingQueue.create();
 ...

now use blockingQueue1 with all standard Queue methods and properties.
