On Ubuntu 17.10 (OpenSSL 1.0.2g), this patch fixes test_poplib error.
But I don't know this patch is right.

Christian Heimes  added the comment:

It's a duplicate of #32706. The new cert validation code causes the handshake 
to terminate properly. The old asyncore based test routine is not able to 
handle this correctly when the machine is under heavy load.

...also, my initial build (after inspecting git log) was from (as I usually do) 
master/HEAD;

To check that this was indeed from v3.7.0b1 release, I `distclean` and checked 
out the v3.7.0b1 tag, and rebuilt.   (Looks like same error / behavior).

New submission from Yarko Tymciurak :

Just built v3.7.0b1, and have the following test hangs (see attached).

My build is on Ubuntu 16.04;  lsb_release -a output:

LSB Version:
core-9.20160110ubuntu0.2-amd64:core-9.20160110ubuntu0.2-noarch:printing-9.20160110ubuntu0.2-amd64:printing-9.20160110ubuntu0.2-noarch:security-9.20160110ubuntu0.2-amd64:security-9.20160110ubuntu0.2-noarch
Distributor ID: Ubuntu
Description:Ubuntu 16.04.3 LTS
Release:16.04
Codename:   xenial

My "usual" config / build process:

$ make distclean
$ ./configure --enable-shared --enable-loadable-sqlite-extensions 
--with-system-ffi --with-ensurepip=upgrade --enable-optimizations
$ make -j

I have been building 3.7 weekly, from master, and I've never seen anything like 
this before.
