We've been able to track this back to legacy PHP bug https://bugs.php.net/bug.php?id=61019 which was fixed via php/php-src@1ec83d4.
This update simply applies the upstream work around to avoid switching to unbuffered mode for pipe streams on PHP < 5.4.28 and PHP < 5.5.12 and thus avoids this issue on all versions. Technically, unbuffered reads aren't really needed here for any PHP version, but not using unbuffered reads shows a 10%-20% performance penalty.
