New submission from Ofer Sadan <ofersada...@gmail.com>:
running `urllib.request.urlopen` multiple times causes the memory usage to
increase with each run, even after calling `close()` on the request or using
`del` on the result
To recreate this problem, run code:
import urllib.request
def ip():
r = urllib.request.urlopen('https://api.ipify.org')
b = r.read()
r.close()
print(len(b))
return b
for i in range(1000):
result = ip()
del result
Even though `len(b)` has a maximum value of 15 (for this url at least), the
memory increases with each run by 200KB - 1MB
