[vtkusers] memory management

[Will Schroeder]

Which operating system? Some systems do not free memory even though you 
invoke delete/free.

VTK undergoes several hundred tests every night checking for memory leaks 
(using Purify) so we know it's pretty clean.

Also try setting the GlobalReleaseDataFlagOn() (invoke this method from any 
data object). This will cause filters to delete data once they are done 
with it.
