Active tasks that are not high priority are waiting for messages to arrive from other devices. If there are active tasks, but no high priority ones, the device may sleep but should periodically wake up and call emberPollForData() in order to receive messages. Parents will hold messages for EMBER_INDIRECT_TRANSMISSION_TIMEOUT milliseconds before discarding them.
