Bug description:Committed memory steadily increasing

Description:
------------
Since upgrading to PHP 7.0.7, committed memory keeps increasing until I
restart FPM, and then it begins all over again. 

I found one other person ("canique") reporting something similar after
upgrading to 7.0.6:
https://www.dotdeb.org/2016/04/29/php-7-0-6-for-jessie/

"Since upgrading to php 7.0.6 I see memory issues. The committed memory
in linux is increasing all the time. I’m checking this with “cat
/proc/meminfo | grep Committed_AS”
To see this bug, it’s important to not restart php-fpm and to have a
high max request count in your php process pool (pm.max_requests). Each
time the php child process is quitting, this memory is of course
released. But if those child processes get multiple thousands of
requests the committed memory is steadily increasing."
