memory leaks

[William Dulyea <wdulyea qualcomm com>]

I am using a notebook with several pages, each page is backed with n_ 
widgets,  each time I switch between pages I want the container of pages I 
am switch from and all its children to be destroyed or un referenced if you 
prefer.  Simply destroying the widget parent does not accomplish this as I 
thought by propagation, oops.  In the mean time I watch my application 
consume more and more memory:(
