Description:
------------
The description of session.gc_max_lifetime (as well as its name) imply 
that it is the maximum lifetime of a session. In actuality it is just 
the session timeout. This problem exists in both php.ini-dist/php.ini-
production and in the online reference manual.

I considered sending a diff but it's not clear to me where to send it.

The current text:

; After this number of seconds, stored data will be seen as 'garbage' 
and
; cleaned up by the garbage collection process.

session.gc_maxlifetime = 1440

Suggested replacement:

; Session idle timeout. If a session is idle for this number 
; of seconds, and PHP's default session handling is in use, 
; the session data will potentially be cleaned up by the 
; garbage collection process. Note that custom session
; handlers can override this (see session_set_save_handler ).
; The default timeout is 1440 seconds (24 minutes).

session.gc_maxlifetime = 1440
