Am I right with the following assumptions?

1. The call to sys_timeout() shall not block the calling thread.

2. Even if the time is over, the system must not call the timeout handler
unless the thread which called corresponding sys_timeout() blocks.

3. After finishing the timeout handler, execution continues with the thread
that has been running before the timeout handler was invoked by the system.

Thanks,

Peter
