I'm not familiar with using NSFileHandle for a TCP oder UDP socket (though
essentially a socket is a file, I prefer to differ between those two).

increase the timeout for sending/receiving.

Maybe, just maybe, you could use NSFileHandle-synchronizeFile to flush the
buffer. But as I said, I do not use NSFileHandle on sockets.
Richard might tell you, though.
