nio2 build 98

[Alan Bateman]

This build is mostly bug fixes and small improvements. It is 
synchronized with jdk7 b40. For those using the asynchronous I/O API 
then it would be good to grab the latest bits as there are number of 
fixes in this build (and the previous build) to bugs that arose under 
load conditions. Thanks to Jean-Francois Arcand for several test cases 
that helped identify some tricky problems. Also thanks to Rémi Forax for 
corrections to the DirectoryStreamFilters class.

Binaries, javadoc, summary of changes are in the usual place [1]
