I guess the main reason is to maintain API compatibility with the
standard socket API. A secondary reason is that receive with timeout
doesn't scale beyond a single socket, and most realistic apps need to
work with multiple sockets.

Thus, we have blocking/non-blocking recvs, and we use a poll semantic
for timing and input/output ready.

You can build timed-out recv wrappers using these APIs, if you need them.
