Detecting remote NIO sockets closed

[Stanley Brown <stanley dot brown at zimmer dot com>]

Found another NIO sockets issue.  For some reason an OP_READ event is 
never issued when a non-blocking socket has concluded.  This is a 
problem because, from my understanding, the only way to know you've 
reached the end of one of these is by recieving an OP_READ and getting a 
-1 back when attempting to read from the channel. 

Example:  http://javaalmanac.com/egs/java.nio/DetectClosed.html

I dug around a bit and I think that the problem resides in 
natSelectorImplWin32.cc:

   aArray[nCurIndex++].init(pReadFD[i], FD_ACCEPT | FD_READ);

Shouldnt we take interest in closing fd's?

   aArray[nCurIndex++].init(pReadFD[i], FD_ACCEPT | FD_READ | FD_CLOSE);
