No. A thread's Execute() method is only called once. If it exits the 
thread ends to never return.
Suspend() uses operating system functionality to stop a thread's 
execution whereever it currently is (dangerous!) and Resume() let's the 
thread continue its execution from that point on. Now with the 
deprecation of these two methods a new method was needed to get the 
thread out of the "create suspended" state. Thus Start() was born 
(internally Start() is basically just an alias for Resume()). It's only 
reason of existance is to start a thread that was created as suspended.
