Andi,

your patch fixes the initial bug that stops sampling immediately after
starting. The issue Eric mentions seems to be a different problem. I
am also not able to reproduce this. Your patch on top of rc3 continues
sampling at least for several minutes.

I will apply your fix.

Thanks Andi,

-Robert
