I am using a Beagleboard XM with QNX 6.5.  In my application I render some content offscreen to a FBO and then render it
 back to the main window surface before calling eglSwapBuffers.  What I have found is that the call to 
glBindFramebuffer() is taking 70 msec.  By doing a kernel trace I can see that my application is reply blocked on 
pvrsrvd for almost that entire time.  I am wondering what pvrsrvd is doing during this time and why it takes so long?
