Doug,

Following up my previous message, I have run the tests with Boost 1.32.0 and 
can see what you mean about a drastic improvement.  The full set of figures 
are:

VC8.0 GOF Observer:   109
VC8.0 Signals 1.33.0: 6203

VC7.1 GOF Observer:   78
VC7.1 Signals 1.32.0: 112109

It's interesting that the Observer pattern is actually slower with VC 8.
