Can I get the following change reviewed please?

http://cr.openjdk.java.net/~michaelm/7131399/webrev.1/ The problem is that poll(2) doesn't seem to work in a specific edge case tested by JCK, namely, when a zero length UDP message is sent on a DatagramSocket. The problem is only detected on timed reads, ie. normal blocking reads work fine. The fix is to make the NETTimeout() function use select() instead of poll(). Thanks, Michael.

Forgot to mention, that the second file in the webrev is a file that needs to be removed from the repo, and which was added unintentionally in a previous merge.

Thanks, Michael.
