[email protected] decided this https://bugs.php.net/bug.php?id=68772 is "not a bug" however be warned:
If you write to the buffer (using print statements, etc.) after calling fastcgi_finish_request(), your script will exit with no error message or exception. Calling ignore_user_abort(true) after fastcgi_finish_request() can mitigate this issue.
