Detecting dropped connections

We have a bunch of processes talking to each other over local TCP connections. On NT we can detect if one of the processes goes away (crashes even) because we get an error from recv() on that socket. But on OS X we do not seem to get an error! Why are these behaviours different and how are we *supposed* to discover that sockets have gone bad?
