Currently r_smp will only work on Mac OS X because SDL 1.2 doesn't expose
the necessary handle for OpenGL context switching.  Mac OS X has some 
functions that allow us to do this without SDL, but X11 does not. 

SDL 1.3 will expose all of the necessary bits for OpenGL context switching,
but it's unclear as to when this will be released  and when ioquake3 will
move to it.

I have been playing with the idea of trying to rewrite r_smp so that 
rendering is done in the main, and frames are processed in a thread 
(the opposite of what is currently done).  However, at this point I have
no idea if this will work.
