After Ian's contex patch/fixes quake3-smp doesn't work anylonger.
Empty black window, no CPU cycles were burnt.
Can you identify exactly which set of changes introduced the problem?  I 
made several sets of commits in this area recently.  I don't have an SMP 
system to test on. :(

- 6/24/2003 & 6/25/2003:
        lib/GL/glx/:
        glxcmds.c glxext.c glxextensions.c glxextensions.h
        compsize.c glxclient.h pixel.c render2.c
        lib/GL/dri/:
        dri_util.c dri_util.h
        programs/Xserver/GL/glx/:
        glxscreens.c rensize.c singlesize.c
        lib/GL/mesa/src/drv/r128/:
        r128_screen.c
        lib/GL/mesa/src/drv/i810/:
        i810screen.c
        lib/GL/mesa/src/drv/i830/:
        i830_screen.c
        lib/GL/mesa/src/drv/mga/:
        mga_xmesa.c
        lib/GL/mesa/src/drv/tdfx/:

        *Lots* of stuff under extras/Mesa/src
        lib/GL/mesa/src/drv/r200/:
        r200_tex.c
- 7/3/2003

The break is probably in this group of changes.  If the problem isn't 
here, then it's probably in the last set of changes (below).

        lib/GL/glx/:
        glxcmds.c 1.45
        lib/GL/mesa/src/drv/r128/:
        r128_ioctl.c 1.27
        lib/GL/mesa/src/drv/r200/:
        r200_ioctl.c 1.20
        lib/GL/mesa/src/drv/radeon/:
        radeon_ioctl.c 1.46
This was the second group on that same day.

        lib/GL/glx/:
        glxcmds.c glxext.c
This last group addes support for GLX_SGI_make_current_read.

        include/GL/:
        glxproto.h
        lib/GL/glx/:
        glxclient.h glxcmds.c glxext.c glxextensions.c
        lib/GL/dri/:
        dri_util.c
        lib/GL/include/GL/internal/:
        glcore.h
        programs/Xserver/GL/glx/:
        g_disptab.c g_disptab.h glxcmds.c glxcmdsswap.c
        glxcontext.h glxdrawable.h glxext.c glxext.h glximports.c
        glximports.h glxscreens.c glxutil.c glxutil.h
        programs/Xserver/GL/mesa/src/X/:
        xf86glx.c
If I had an SMP box I'd be able to track this down on my own.  Instead 
all I have are these stinking nearly-top-of-the-line uniprocessor boxes. :)
