But that patch was about shred whereas this bug report is about dd.

But on second thought I reverted the dd patch, which was a bit 
speculative anyway. After all, if CLOCK_MONOTONIC freezes, 
CLOCK_REALTIME is likely to freeze as well.

Sick Pigs, you're welcome to try the patch anyway, and if it works for 
you (which I now hope it doesn't ...) we can reinstall it.
