Description:
------------
It is unclear from the documentation from which point in time 
the ttl settings are used. Is it from the time the cache 
entries are created or modified, or from the last time they 
are accessed?

The documentation uses the phrase "idle in a slot", but does 
not specify what it means for an entry to "idle". i.e. does 
the act of accessing, but not modifying, an entry count as an 
action that stops idling?

The settings in question are:

apc.ttl
apc.user_ttl

I was confused by the terminology too, but I think that you just need to interpret 
idle as 'not used', where used = created/modified, or accessed. So a read(hit) 
will reset the counter, and a write(put) will also do so.

With APC dead, I don't this is something anyone will ever work on as no stable version of PHP today are supported by APC
