Thanks for the patches you supplied.  If I understand correctly, a  
subset of that patch was applied to the repository and this resolved  
some of the problems with the memory leaks.  Please get back to us if  
you need clarification.

ObjectHandler has no dependency on QuantLib.  There would be nothing  
preventing us from copying the new improved observable.hpp from  
QuantLib to ObjectHandler.
