Spread doesn't have any sort of timeout regarding how long it will
hold messages before delivery. "Delivery" basically means that Spread
has written the message to the client's socket. If the buffer is
full, Spread will queue an additional number (1000, if I recall, but
it should be defined in one of the headers) before disconnecting the
What this means is that you're probably better off using some sort of
I/O multiplexing, like John suggested. If you don't, the ideal
timeout is really defined by your application's throughput and flow
