// Asynchronous completion notification
// We use window messages posted to hAmigaWnd in the range from 0xb000 to 0xb000+MAXPENDINGASYNC*2
// Socket events cause even-numbered messages, task events odd-numbered messages
// Message IDs are allocated on a round-robin basis and deallocated by the main thread.
// WinSock tends to choke on WSAAsyncCancelMessage(s,w,m,0,0) called too often with an event pending
// @@@ Enabling all socket event messages for every socket by default and basing things on that would
// be cleaner (and allow us to write a select() emulation that doesn't need to be kludge-aborted).
// However, the latency of the message queue is too high for that at the moment (setting up a dummy
// window from a separate thread would fix that).
// Blocking sockets with asynchronous event notification are currently not safe to use.
