I've just done a quick review of the code and master and 3.6 branch do mostly seem to be doing what they should in the Text/Font::releaseGLObjects(). There is one area that does look like it might be missing some releaseGLObjects() calls is in the handling of Glyph3D objects. However, in your example where you were playing games with globals to prevent destruction, this remains the wrong way to implement viewers and is not supported by the relaseGLObjects() scheme, for reasons I've outlined in my replies above.
