Sometimes when chasing issues under apitrace I get stuck in the loop in checkGLError - I guess that (somehow) bad is happening. Nevertheless - it seems unlikely to me that we really need an infinite loop here - so chop it down to 8x errors per call: we call it rather regularly so ... we should bail out here if we can.
