Here is 3 PYs, we found there is a big memory wasting, specially the program
c.py, we found the memory will increase very soon.

You are creating reference cycles and instantiate many in very short time.
Objects with cyclic dependencies must be detected by the garbage collector
which takes some time.

Usually this is not a problem because generating lots of cycles in a tight
and endless ``while``-loop is not *that* common. ;-)

You may take a look into the `weakref` module to avoid the cycles.
