Summary: Insane amount of memory lost in FromXml

Initial Comment:
calling FromXml uses an INSANE amount of memory.  the
larger the document, the more memory is lost.  here is
a demonstration that uses Cyclops.py (found from
searches on python.org for memory usage).

#!/usr/bin/env python
"""
"""
resdata = """<root >
<Schema name="Schema1" >
</Schema>
</root>
"""

from xml.dom.ext.reader import Sax2
from Cyclops import CycleFinder
def test():

    z = CycleFinder()
    d = Sax2.FromXml(resdata, validate=0, keepAllWs=1)
    z.register(d)
    del d
    z.find_cycles()
    z.show_stats()
    z.show_cycles()
    z.show_cycleobjs()
    z.show_sccs()
    z.show_arcs()
    print "dead root set objects:"
    for rc, cyclic, x in z.get_rootset():
        if rc == 0:
            z.show_obj(x)
    z.find_cycles(1)
    z.show_stats()

if __name__ == '__main__':
    test()
