Suspend a task, with time-out provision.
Wake a suspended task.
Forcefully wake a task.
Change a task's priority.
Terminate a task early.
Do a cooperative rescheduling.
Disable task scheduling.

Clear an event.


MESSAGE MANAGEMENT
Get a message.
Wait for a message, with time-out provision.
Send a message.
Send a message, wait for reply.
Wake task that sent message, if waiting on reply.
