Thank for this. I can confirm it works with the modified test code I attached to
the ticket. I am ts-validation-no-clock-0.exe now failing on xilinx_zynq_a9_qemu
but I am not sure?

There is one issue my test changes have exposed and that is the ticks a thread
sleeps for is 1 more than the requested number.
