[New-bugs-announce] [issue19443] add to dict fails after 1, 000, 000 items on py 2.7.5

[Milton Mobley]

New submission from Milton Mobley:

d, i = {}, 0
while (i < 10000000):
    n =  i + 1
    d[n] = n
    i += 1

On Py 2.7.5 (windows7, x64, 4GB ram) this program slowed down obviously after passing 1,000,000 adds and never completed or raised an exception.
Windows performance monitor showed it was only claiming about 1 MB memory per second, and stopped claiming more memory at about 646MB. The only other large memory consumer in the system was JRE using about 550 MB on behalf of Eclipse.
