Comment 75 for bug 1011792

Somehow I had hoped to find some way to understand why the fix works (or what exactly goes wrong without it). But then other things and bad long-time memory (sort of) came into play and this has not really progressed much. So I try to actually get this into Precise at least (since no testing seems to have found any bad side effects). Still need to follow-up on this for current kernels (if the testcase still fails there).
