Hello all.

	When, in Squeak, I go to "Load Code Updates", the updates start to load,
and then I get a stack trace titles MessageNotUnderstood: resolverMutex 
and Squeak freezes.  It doesn't lock hard, as it still redraws and I can
click the close icon of the window to exit, but I can not interact with
it.

	Any help?  I'm running Squeak3.1alpha, latest update #4173, Current
change set: 3880HaltUpdates-tk, under linux.

	Thanks!
