Thanks Ben, does a return code of true and the callback being called mean
exactly the same thing? Do both give the same guarantee?

The reason I ask is because I am pre-allocating a buffer for a websocket
server, and this is overwriting the buffer as soon as write returns true or
the callback is fired. I noticed that for large writes it's overwriting
data before it gets to the client.
