So that's weird. The client gets the initial ref advertisement and then...does nothing? It should drop into find_common() and start sending want/have lines to the server (or decide it doesn't need any objects and immediately send a flush packet).

Is the client chewing any CPU, or otherwise doing anything according to "strace"? Is it possible to connect to it with gdb and get a backtrace?
