Just one minor comment: you added some javadoc comments in the middle to mark 
the different phases, we should make them regular comments.

I am sorry.  I do not understand this comment.  Are you referring to {{Simulate 
grabbing 2 threads}} ?? If so, this is the appropriate comment format.

I think it is more clear calling {{Math.abs}} than to introduce a magic number 
and assuming that everyone understands basic math :)  I'm not sure what about 
this you do not like.

I hope you will consider accepting the latest patch.  I very much appreciate 
all your feedback and time.
