[New-bugs-announce] [issue37702] memory leak in ssl certification

[neonene]

New submission from neonene <nicesalmon at gmail.com>:

Windows10/7(x86/x64)
After issue35941 (any PR merged)

In https-access, memory usage increases by about 200KB per urlopen()
and easily reach to giga bytes.

I found out leak of certificate-store-handles in _ssl.c and made patch,
which works fine for my pc.

I guess some users are in trouble with this leak.
I'm about to raise PR, so please review. Thanks!
