This is basic C++.
Once you allocate something on the heap using new in some part of the code
you will have to delete it.
Wt gurentees that it mangaes all memory, and deletes the widgets at the end
of the session.
I suggest you to read about
RAII<http://en.wikipedia.org/wiki/Resource_Acquisition_Is_Initialization>and
take a close look at smart pointers, especially boost's shared_ptr.
Think about it, if you allocate some object without deleteing it (some
non-related Wt object for example) there is no reason it won't cause a
memory leak.
If you are on linux I also suggest you to use valgrind to inspect such
things, it will prove you that there is no memory leak in the code.
