test case program that aborts if glRenderMode() call takes long time to
execute.

Hi,

I have found high latency on GL_FEEDBACK glRenderMode func.

When using feedback mode, sometime my prog is locked for seconds. 
This latency is introduced when using glRenderMode func.

I enclosed a single test case able to reproduce the problem.
This problem has not appeared on other distributions, or systems I am using.

It happens either using Intel DRI driver or when forcing mesa software API
rendering, using LIBGL_ALWAYS_SOFTWARE=1 env. variable.

Regards,
S.Ancelot
