Expose zend_message_dispatcher_p

Great! I always glad to help. And I would avoid "tricky" solutions as much
as possible. :)

Even 2 minutes TTL is going to save few thousands syscalls, in case your
site is really
high loaded, and it make no sense to care about "last syscall optimization"
if you system is mostly idle.

BTW: I'm not sure if APC calls stat() for inclode_once(), but it definitely
possible not to call it.

Thanks. Dmitry,

Hey:

This problem come out when I was figuring a performance issue of
Yaf_Loader.

Yaf provides a autoloader like PSR0, when doing a classes
autoloading. it used to:

1. stat the file, if file does not exists, return
2. zend_compile_file

this is okey when you run yaf without opcode cache.

but when you run yaf with opcode cache, the first stat syscall
become a little waste.

You should just use virtual_realpath() or tsrm_realpath() instead of
stat(). They must utilise realpath cache and avoid stat() calls.
Hey:

Thanks, Dmitry,

actually, I didn't do like that is because by default, realpath
cache has 2min ttl.

but, after a second think, I think this will be better than my
current tricky implementation.. I will try in this way :)

thanks

Thanks. Dmitry.

since opcode cache always hook the zend_compile_file, and compile
the file from cache.

so, I changed the autoload to:

1. zend_compile_file
2. if compile failed, then return.

but, zend_compile_file will throw warning if the file doesn't
exists via zend_message_dispatcher_p

so if zend_message_dispatcher_p is ZEND_API, then I can avoid using
such mess codes:

what do you think?
