I hate to reply to my own thread but I wanted to update it. I tried
the same code using ctypes arrays and see no memory leak:
import commands
import array
import itertools
import sys
import ctypes
from itertools import repeat
from ctypes import *
print '*** before ***'
print commands.getoutput('cat /proc/meminfo').split('\n')[1]
for i in range(100):
a = ARRAY(c_uint, int(2E6))
del a
print '*** after ***'
print commands.getoutput('cat /proc/meminfo').split('\n')[1]
*** before ***
MemFree: 1416364 kB
*** after ***
MemFree: 1416364 kB
