[vtkusers] vtkUniformVariables memory leak

[Cory Quammen]

The short answer is that there shouldn't be any memory leaks, but it
is always possible that there is a bug in VTK.

Can you post a small example (.cxx file, CMakeLists.txt file) that
exhibits this behavior? It will make it easier to help you debug.

Thanks,
Cory
