Use NET_TCPSocket instead of UT_NetSocket. UT_NetSocket has a lot of short comings when something unexpected occurs. UT_NetSocket also doesnt support async very well. Additionally, its very difficult to get proper error information when something goes wrong.

Performs a select() call on the socket.
Note, it turns out there is a discrepancy between how select() works on Linux vs. Windows.
On Windows, the select() call selects for reading the sockets even if they were closed by the remote counterparts. The rationale is that trying to read from such a socket returns zero, which is a signal that the connection was closed.
On Linux/OSX, select() call does not select such sockets for reading. The rationale is that there cannot be any more data for reading on closed sockets.
