/**
* \brief Let mote execute one "block" of code (tick mote).
*
* Let mote defined by the active contiki processes and current
* process memory execute some program code. This code must not block
* or else this function will never return. A typical contiki
* process will return when it executes PROCESS_WAIT..() statements.
*
* Before the control is left to contiki processes, any messages
* from the Java part are handled. These may for example be
* incoming network data. After the contiki processes return control,
* messages to the Java part are also handled (those which may need
* special attention).
*
* This is a JNI function and should only be called via the
* responsible Java part (MoteType.java).
