The snapshot build seems to have fixed the original issue I was encountering, but it seems it might
have created a new one... Or maybe this one existed already, and I just hadn't managed witness
it before.
Again only on an encrypted connection... If the server waits for more than default_socket_timeout
before starting to receiving data, while in the mean time the client does a stream_select() with the
connection in $w (i.e. it waits for the server to be ready to receive... supposedly), and $tv_sec
being NULL, stream_select() just hangs at the client, and thus no sending is ever done.
Though for some reason, I can't duplicate it by modifying the echo client/server pair from bug
#68853 accordingly... Feel free to close this particular issue. I'll create a new one if I can
produce a more reliable test case than my current (somewhat large) original code that exhibits this
new issue.

Windows snapshots should be available sometime in the next few hours here:
http://windows.php.net/downloads/snaps/php-5.6/
The commit to fix this was added after the final March 05 snapshot. As soon as a newer snapshot is
available you should be able to download a usable windows binary to test. In my own tests this
latest commit resolves the issue from the client/server test case in the related bug #68853.

Thank you.
I don't have the setup (or know-how) to compile PHP myself, especially on Windows. If there
were snapshot builds, I'd gladly test this, as well as the related #68853.
I guess I'll just have to wait for... 5.6.8 or whenever a release with that fix in it emerges,
and report back then, if there are new issues.
(Considering how long this has been an issue, I don't mind...)

I have cherry-picked @DaveRandom's original SSL_pending() solution back into 5.6 and master.
I'm fairly certain this commit solves the problem fully. It was unfortunately reverted due to
its close proximity to some other buggy shenanigans.
This change will *not* appear in the forthcoming 5.6.7 release so that we have time to test, get
feedback and verify that it works everywhere. If you're interested in this bug's
resolution please build the current PHP-5.6 or master branch to verify that the issue is resolved.
