Included is a patch that adds a PHP_FCGI_TIMEOUT that works
somewhat akin to PHP_FCGI_MAX_REQUESTS. With PHP_FCGI_TIMEOUT
set to 300 the whole fcgi process will terminate after 300 sec
with no request to any of the worker children - great for those
seldom used dynamically created fcgi scripts.
Cheers,
/Chris
PS. The patch works just as well in 5.0.2 as in 4.3.9.
