Things that'd be interesting:
1) what are the arguments passed to WaitLatchOrSocket(), most  importantly wakeEvents and sock
2) are we busy looping, or is WaitForMultipleObjects() blocking  endlessly
3) If you kill -9 (well, terminate in the task manager) a client, while  stepping serverside in WaitLatchOrSocket, does
WaitForMultipleObjects() return? If so, what paths are we taking?
