Another issue that might be of concern is whether a slot is being
disconnected from a signal in one thread while a value is being sent
through that same signal in another thread.  If the one thread is
iterating through the connected slots while the other is removing a
slot from the list, unexpected behavior/crash might occur.

Doug said that some people have recently been working on Boost.Signals
and specifically addressed thread safety, but I'm not sure what the
status of that is.
