[vtkusers] vtkCollection->RemoveAllItems() not freeing memory on Windows

[Andrew Wilford]

Hi,

After examining the source for vtkCollection->RemoveAllItems(), I was under
the impresion that this function deleted all members of the collection
first. However, analyis of the memory used under Windows 2000 shows this not
to be the case. Subsequent use of the same collection (member variable of a
class) causes memory usage to increase with each iteration.

How do I successfully free the memory associated with vtkCollection?
