David B. Kinder 60136f00cb doc: add how to exit from QEMU in samples While trying out the hello_world sample built for QEMU, I was expecting the sample app to exit and I'd return to a command prompt. Nope. You need to exit QEMU manually, so add that step to the sample instructions. Looking around, there are more uses of QEMU like this that could use this added step after running the sample app. Signed-off-by: David B.

Synchronization using CMSI RTOS V1 APIs
#######################################

Overview
********
The sample project illustrates usage of timers and message queues using
CMSIS RTOS V1 APIs.

The main thread creates a preemptive thread which writes message to message queue
and on timer expiry, message is read by main thread.


Building and Running Project
****************************
This project outputs to the console.  It can be built and executed
on QEMU as follows:

.. zephyr-app-commands::
   :zephyr-app: samples/philosophers
   :host-os: unix
   :board: qemu_x86
   :goals: run
   :compact:
