GWorkspace hangs on first exit attempt. Remote objects problem?

[Riccardo Mottola]

Hi,

some of you may have noticed that GWorkspace sometimes do not exit at 
the first attempt, but at the second. It does not happen on all 
computers, but on those where it does, it happens consistently. I and 
Sebastian did a "NSLog debugging", my previous attempts with gdb where 
unsuccessful.

in GWorkspace, in applicationShouldTerminate, we have this code:


  if (fswatcher) {
    NSConnection *conn = [(NSDistantObject *)fswatcher connectionForProxy];

    if ([conn isValid]) {
      [nc removeObserver: self
                      name: NSConnectionDidDieNotification
                    object: conn];
      [fswatcher unregisterClient: (id <FSWClientProtocol>)self];
      DESTROY (fswatcher);
    }
  }

the problematic line is:
[fswatcher unregisterClient: (id <FSWClientProtocol>)self];

When this GWS hangs, it hangs because this line does not return. 
fswatcher is the daemon object.

fswatcher will exit with exit() when the last client unregisters and in 
this case it is happening, we checked the code-path and also "ps" shows 
that it indeed exists. Why does it hang? And why does it hang on certain 
machines only?

I fear there could be a base problem, when invoking remote objects?
