Hmm, so if I run 'watch -n 1 date' in qemu and on the host, in the time
10 seconds pass in qemu, 25 seconds passed on the host.  qemu thinks it
is running as fast as before, but its concept of real time is wrong.

With the build I did on january 14th, the qemu and the host are in sync
timewise and qemu is way more responsive (at the cost of a lot of cpu of
course).
