Bug description:Sending php-fpm service a HUP signal causes problems with
daemontools
Description:
------------
I'm running php-fpm with DJB daemontools (daemonize = no) process
supervisor.
Every time I send the process a HUP signal (graceful reload) the process is
in some way "detached" from daemontools so it's not possible to reload it
because it's already runninng.
Since the children processes aren't properly (?) terminated, php-fpm
refuses to start:
Test script:
---------------
