Ok, it seems partly a false alert. I tried combinations streamfs+vmpatch 
and sard+streamfs. Both worked just fine so the combination of vmpatch
and sard patch seemed to trigger the problems.

It seems the drop-behind stuff is still not very tuned. Compare with 
hdrbench30x10.png and you'll see the difference. Infact hdrbench aborted
the test because of buffer overflows.
