Function 'sys.setcleanuphook' -----------------------------

A new function for the sys module is proposed.  This function sets a callback which is executed every time fincleanup becomes false.  Callbacks get a frame object as their sole argument, so that they can figure out where they are called from.

Calling a function every time you leave a finally block? Isn't that a bit expensive?
