Summary: memory leak in xml.parsers.sgmllib

Initial Comment:
The following short test program is leaking memory:

from xml.parsers.sgmllib import SGMLParser

while 1:
    p = SGMLParser()


There is a cross reference cycle between
sgmllib.FastSGMLParser and sgmlop.SGMLParser
which is not detected by the garbage collector.

Breaking the cycle with the following workaround
stops the memory leakage:

while 1:
    p = SGMLParser()
    p.feed = None
    p.parser = None



(environment: PyXML 0.8, Python 2.2.1, Linux 2.4.3)
