The example crashes also with functions like but it takes a bit longer

def alloc():
   while 1:
       a = {}, {}, {}, {}, {}, {}
       time.sleep(0.011)

def alloc():
   while 1:
       # create 500 bound methods to exceed PyMethod_MAXFREELIST 256
       methods = []
       for i in xrange(500):
           methods.append(str("abc").strip)
       time.sleep(0.011)

Does it crash as easily with Python 2.6 ?
If not, then that could be an answer as to why this wasn't noticed before.
