When injecting rapid resets, we must be careful to at least wait for the previous reset to have taken effect and the engine restarted. If we perform a second reset before that has happened, we will notice that the engine hasn't recovered and declare it lost, wedging the device and failing. In practice, since we wait for each hanging batch to start before injecting the reset, this too-fast-reset condition can only be triggered when moving onto the next engine in the test, so we need only wait for the existing reset to complete before switching engines. v2: Wrap up the wait inside a safety net to bail out in case of angry hw.
