Phenotype is updating the flags while this test is running
and this DoS'es the device to such an extent that the test
process doesn't get the CPU for more that 300ms. That lets
the lingering timeout run its course and fails the test.
This won't necessarily fix all flakes (after all, if
Phenotype hogs the CPU for 2 seconds the same issue will
continue to happen), but it should help.
