Hi

If each thread is a kernel thread, i.e it has its own (heavyweight) process, then you have several processes accessing OpenGL at the same time. I don't know what you're sharing and what you mean by "renderer". You can only have a single process or thread communicating with OpenGL at a time even though you can share an OpenGL context on several processes or threads under GNU Linux.
