------------------------------+-----------------------------
The message queue handler uses the thread queue extract operation to
dequeue a receiver thread. This is wrong in SMP configurations since the
extract thread queue operation does not ensure FIFO fairness across
schedulers. The thread queue surrender operation should be used instead.
