Is garbage collection supposed to run when Python exits? The following program does not print any output, unless I uncomment the gc.collect() (or add a for loop that forces GC after creating the cycle):

import gc

class A: pass

class B: def __del__(self): print "Bye-bye!"

a = A() b = A() a.b = b b.a = a a.x = B()

del a del b

#gc.collect()

One possibility is that the __del__ method *is* being run, but after sys.stdout & so on has been torn down. python -v can help, maybe?
