Milestone: zero open API issues

[Brian Goetz]

We have reached the milestone of "zero open API issues" for Lambda 
Libraries!  The last two open issues -- comparator combinators, 
AutoCloseable -- are now entering the review process.

I still need the help of the EG to review (and contribute to!) the specs 
for java.util.stream.  Candidate docs have been up for a month at:
   http://cr.openjdk.java.net/~briangoetz/doctmp/doc/

Please, try to review at least the Javadoc for Stream and the package 
doc.  We all know how this API is supposed to work; what we need to do 
now is make sure that our documentation conveys that spirit, and 
effective examples, for helping people "get it".
