We've recently seen some slowness here that affects the clock. So far
I think it's only been seen on multiprocessor (multicore) AMD64
systems with Realtek 8169 Gb Ethernet. Setting *ncpu=1 fixes the
problem at the cost of using only one processor. When we tried to add
debugging to the kernel to track this down, the problem vanished.
