Or you write, write, write in quick succession. Nagle's Algorithm
means that if the first one hasn't yet been acknowledged, the second
one will be delayed, which means it'll probably be combined with the
third and sent when the first one's ACK comes through. Stream sockets
guarantee a stream of bytes; datagram sockets guarantee datagrams.
Weird how that goes, isn't it?
