If the value is a time!, delay for that period. If the value is an integer! or decimal!, wait that number of seconds. If the value is a port!, wait for an event from that port. If a block! is specified, wait for any of the times or ports to occur. Return the port that caused the wait to complete or return none if the timeout occurred.
