The "Access denied" issue that you ran into with the Windows 7 firewall
is, in my mind anyway, obscure and probably impossible to differentiate
from a serious implementation bug. It's also not clear to me what
recovery action you could take that would be different to other I/O
errors. The only case that I think we should add a specific exception
for is the "reset by peer" case (that applies to SocketChannel and
legacy Socket aswell).
