The external opengl context must be specify when creating our OpenGL context (glx) or just after (wgl). When calling glXCreateContext or wglShareLists, the external opengl context must not be current. Then our gl context can be current in the gl thread while the external gl context is current in an other thread. See tests/examples/clutter/cluttershare.c
