[Python-Dev] memory leaks

[Charles G Waldman]

The following code (extracted from test_extcall.py) leaks memory:

class Foo:
   def method(self, arg1, arg2):
        return arg1 + arg2

def f():
    err = None
    try:
        Foo.method(*(1, 2, 3))
    except TypeError, err:
        pass
    del err



One-line fix (also posted to Sourceforge):

I think that there are a bunch more memory leaks lurking around...
this only fixes one of them.  I'll send more info as I find out what's
going on.
