RunProcess polled the child with an exponential backoff that capped at 100 ms, so every test longer than roughly 300 ms paid 30-75 ms of latency after it had already exited. Across the parallel suite that adds up to about 160 thread-seconds. Block in wait() instead and let a timer thread deliver the kill when the timeout is crossed. Set the shutdown flag from the SIGINT handler so a worker whose child died from the same ctrl-c does not report it as a failure before the main thread aborts the run.
