[SQLObject] Memory leak?

[Martin d'A. <Mar...@s2...>]

Hi,

I think I have found a memory leak. I have a loop that inserts hundreds of 
thousands of rows in my table, and the memory usage grows eventhough I 
do not keep a handle to the instances I am creating. For example, the 
following program will use more memory when you tell it to store more rows 
in the database:

#!/usr/bin/env python

import sys
from sqlobject import *

class Persons(SQLObject):
    name = StringCol(length=4)

def create_table(conn):
    Persons._cacheValues = False
    Persons._connection = conn
    Persons.dropTable(ifExists=True)
    Persons.createTable()

def fill_table(size):
    for i in xrange(int(size)):
       p = Persons(name='Joe'+`i`)

if __name__ == '__main__':
    size = sys.argv[1]
    conn = connectionForURI('mysql://user:passwd@server/test')
    create_table(conn)
    fill_table(size)


At the prompt, just type "persons.py <number>". The bigger the 
<number>, the more memory is used. Is there a solution?
