/* this is to test what happens when gettimeofday is overridden. On
an idle machine, a little more than one second ticks every hour.
The dongle is still required but it does allow the emulator to run
w/o a license. However there are several bad time-related
side-effects. The worst seems to be that timeslicing doesn't work,
so a CPU-bound job more-or-less locks up the machine.
