Added API to check if in interruption. Added more internal check if in interruption checks. Fixed pathological sleep disorder on iOS problem...bug was I forgot to convert microseconds to milliseconds in usleep calls which led to very short sleep times and the pathological sleep disorder problem. Thanks so much oto Kapil K. for spotting this problem for me.
