Python takes great care to make sure all builtin operations are threadsafe,
and tries to make it as easy as possible to make your own extensions
threadsafe. As long as you write Python, you're very threadsafe, because
only one thread can execute Python code. If you start writing extentions, in
C, or embedding Python in a multi-threaded program, things get a little more
complicated, though, and you'll have to pay attention to where you allow
multiple (Python) threads to execute.
