Currently, if you create a thread through the thread module
(rather than threading), it won't participate in the "wait until
all threads are done" algorithm - you have to use the threading
module. Moving it into the thread module would allow to cover all
threads.

Also, if the interpreter invokes, say, threading._shutdown():
that's also "user-screwable", as a user may put something else
into threading._shutdown. To make it non-visible, it has to be
in C, not Python (and even then it might be still visible to
extension modules).
