Is __del__ supported? Is garbage collection working?

tinypy is amazing.  Very nice to see such a concise implementation
of python!

What steps will reproduce the problem?

1. try to run this code:

ndel = 0

class rect:
    def __init__(self, orgx, orgy, sizex, sizey):
        self.orgx = orgx
        self.orgy = orgy
        self.sizex = sizex
        self.sizey = sizey
        self.list = [];
        for i in range(10):
            self.list.append(i)

    def __del__(self):
        print("del")
        ndel = ndel + 1

for i in range(1000):
    a = rect(0,0,100,100)
    b = rect(0,0,100,100)
    b = a

print("__del__ called " + str(ndel) + " times")
print("bye")

What is the expected output? What do you see instead?

I was expecting __del__ to be called like in cpython.  Is garbage collection
working?  I added printf to gc.c and it shows these functions being called,
but the __del__ function is not being called.

After adding some printfs it looks like garbabge collection is happening fine, 
the problem is that __del__ is not being called.  Maybe if I study the source I 
can make it work...
