Description:
------------
Now that there is the apc.stat flag (which is great BTW), it 
would be handy to have something like apc.stat_filters so you 
could stat some files, but not all.

Another thing that would make this really useful would be 
extend apc_clear_cache() so you can flush just a single file 
from cache (maybe stat is off, but you updated a file and 
don't want to flush everything).

The no-stat only works for absolute-path includes, so anything you include with a relative path (anything that doesn't start with /) will be stat'ed.  Of course, for top-level files you don't have that option, but you could definitely build things such that the changing parts were in an include file.  But yes, I agree, both of these would be useful.

Another thing that might be nice would be some sort of 
apc.stat_minimum_time parameter.  So you could tell the system 
to maybe stat files once in awhile (like hourly or something), 
but not with every request.

The apc.stat_minimum_time parameter idea seemed good at first, but broke down the system completely when multiple dependent files were thrown into the mix. I have similar reservations about single file cache clears.

The current ~2 second window seems acceptable, while in no-stat mode (or hourly stat mode) it is just too high. Rather than go half-way into state differences between disk and cache, I'd prefer to keep status quo. 

Hope you understand.
