Well after I write this extension I was talking about we'll know
if it's a client resource leak or not. Render has a resource for
GlyphSets and adds Glyphs to it. When the client dies the GlyphSet
gets freed and hopefully all the Glyphs associated with it get freed.
One test to do with KDE would be to start without a window manager
(just run X) and then "startkde". If you kill KDE and the usage
goes down, that would be indicitive of a resource leak in KDE.
Mark.
