* thread1
*
* Tests for:
* osStopThread
* osStartThread
*
* Assumed working:
* osCreateThread
* osYieldThread
* osCreateMesgQueue
* osSendMesg
* osRecvMesg
* osGetIntMask
* osSetIntMask
*
* Description:
* Check that osStopThread takes thread off run queue
* Check that redundant calls to osStopThread have no effect
* Check that osStopThread does not affect interrupt mask
* Check that osStartThread puts thread back on run queue
* Check that osStopThread with a NULL argument stops running thread
