With default HZ=100 on a fast amd64 host an Anita test run can take like 6
hours instead of ~1h-2h on semi-fast real hardware. It gets stuck waiting for
response/timeouts from emulated disks and similar, can hit you everywhere.
You really don't want to go there. With HZ=1000 it works fine.

Someone(tm) should really do the tickles work...
