crashes here too....

you shouldn't try to de-couple the execution of the render-chain from 
the "gemclock".
whenever [gemhead] sends out the gemlist-message, it is assured that the 
openGL-context of the gem-window is the current one.
if you call it "sometimes else", this cannot be guaranteed any more.

if you want full control over the render-cycle, you could do something 
with single-buffered mode (but i guess this is broken :-()
