[vtkusers] Free x server memory

[Francois Bertel]

Hello,

If there is a leak in the Xserver after the vtk based program exit
then this is out of the scope of VTK.

It can be a bug in your X server or it can be some result that the X
server caches (it can cache a database of fonts and symbols).

What happen when you start/exit another application regarding the X
server memory consumption (try a big app like Firefox, try an
OpenGL-based app like glxgears)? How do you measure this memory
consumption?

What's your OS, graphics cards, graphics card driver?
