/**
 * Creates a Thread with runnable and starts it. Waits at most timeoutMS for it to finish before sending an
 * interrupt. If waitAfterInterrupt is true, it then waits at most timeoutMS for the thread to finish.
 *
 * Important: Due to the nature of Java Threads the runnable might still be executing in the background after
 * this method has returned. There is not hard shutdown of the runnable.
 * @param runnable the job to run in a limited amount of time.
 * @param timeoutMS the amount of time to wait for processing to finish.
 * @param waitAfterInterrupt if true, there will be a new timeout after interrupt has been called.
 * @return true if the runnable finished within the timeout, else false.
