Ok, the only problem I have with this is the fact that when I use this for
a socket mechanizm and the socket becomes available for writing, even
though I may not have something to write, this call back will be called
over and over and over again, is this true? Is there a way to prevent the
callback from being called unless there is data to actually write to the
socket?
