I have noticed that I always get a segmentation fault if I use the openGL 
versions of the sinks. This seems to be dependent on the graphics chipset, I 
have two computers both with Intel G965.

The segfault can be avoided with LIBGL_ALWAYS_INDIRECT=1, eg,
$> LIBGL_ALWAYS_INDIRECT=1 usrp_oscope.py
Although this slows things down a little bit, it should still be faster than 
pure software rendering.

I would be interested in reports from other people, especially which 
chipsets/drivers segfault and which dont.
