Instead of using delayer device user 'zero' device and let mirror do some real work which takes some time. In case the test machine is too fast - mirror might need to be made bigger to meet needed criteria. Also move all test needed this 'zero' PV trick to the end of test so $dev2 and $dev4 are covered with 'zero' and can take any amount of write without consuming any real space.
