AFAIK supervisord doesn't actually fork anything - it runs daemons it
monitors by creating subprocesses and monitor it directly - removing
need for regular check on pidfiles. (hence I mentioned to take care on
mysql since it ignores quit signal to main process[1] - mysql can only
be stopped by killing the certain process mysqld spawned)

Depends on the platform - and as long fpm is not in official
repository it'll be difficult to setup especially on certain platforms
(OpenSolaris comes to mind). This should be better after 5.3.3 release
but it'll take some time before getting integrated into distributions
and OSes official repository.
