No. msleep(1) is just making that thread go to sleep. It just so happens that 
1ms is ages for modern CPUs and so the kernel decides to switch context to 
another thread/application rather than wasting a whole ms of CPU time.

The yield function just says to the kernel "you can do a context switch if you 
like but I am not going to force you".

Is that clear?
