OK so I have created a vagrant simple proxy: https://github.com/elico/squid-php-helper-tests
It works with REDIS and can be tunned for production use. It's based on Oracle Enterprise Linux 8 and seems to do the job. Anyone is interested in trying to help testing if PHP is still leaking?

FTR, the old problem was not stdin itself. The issue was that PHP was designed with the fundamental assumption that it was used for scripts with very short execution times. Implying that all resources used would be freed quickly. This assumption resulted in scripts (like helpers) which need to run for very long times having terrible memory and resource consumption side effects. Naturally that effect alone compounds badly when Squid attempts to run dozens or hundreds of helpers at once. Later versions (PHP-3/4/5) that I tested had various attempts at internal Zend engine controls to limit the memory problems. Based on the same assumption though, so they chose to terminate helpers early. Which still causes Squid issues. PHP config settings for that Zend timeout were unreliable. AFAIK, That is where we are with knowledge of PHP vs helper usage. PHP-6+ have not had any serious testing to check if the language updates have improved either resource usage or the Zend timeout/abort behaviour.
