If I write the code for the threads then what exactly is the
As far as I can tell, implementing thread killing is something that
is difficult to implement in the interpretter, but rather than just
admit that, we get the "who will think of the newbies" cries instead.
Anybody can use os.remove. Do we prevent access to that? Heck,
I can subclass and not call parent constructors. Does Python

I can make multiple threads of execution and put in all
