@Roddy - Synchronous sockets are not what I'm after. Burning a whole thread for the sake of a possibly long-lived connection means you limit the amount of concurrent connections to the number of threads that your process can contain. Since threads use a lot of resources - reserved stack address space, committed stack memory, and kernel transitions for context switches - they do not scale when you need to support hundreds of connections, much less thousands or more.
