For demonstartation puposes, I attached the simple patch for MMapDirectory that uses the new
StandardOpenMode and FileChannel.open() provided by Java 7. I did not yet really test the
deletion of open files on windows, but all tests pass (as they should).

This patch looks great!

> I have implemented 3 Directory subclasses using NIO2 API's (available on JDK7).  These
may be suitable for inclusion in a Lucene contrib module.
> See the mailing list at http://lucene.markmail.org/thread/lrv7miivzmjm3ml5 for more details
about this code and the advantages it provides.
> The code is attached as a zip to this issue.  I'll be happy to make any changes requested.
 I've included some minimal smoke tests, but any help in how to use the normal Lucene tests
to perform more thorough testing would be appreciated.
