advantages, as you can terminate the loop at any moment by setting
<CODE>CPUIsRunning=0</CODE>. Unfortunately, checking this variable on
every pass takes quite a lot of CPU time, and should be avoided if
possible. Also, <B>do not</B> implement this loop as

because in this case, some compilers will generate code checking whether 
<CODE>1</CODE> is true or not. You certainly don't want the compiler to 
do this unnecessary work on
