you're working below the reliable stream level, you can't just do a >
blocking 'read' for a packet; it pretty much has to be asynchronous
Oh,
you should look at the early BBN TCP for V6 Unix - they would have faced the same issue,
with their TCP process. They did have the capac() call (which kind of alleviates the need
for non-blocking I/O), but that may have only been available for ports/pipes; I'm not
sure if the ARPANET device supported it.
