Subject: Re: [PHP-DEV] [RFC][Discussion] Add session_gc()

Hi!

> Lack of proper API for required task is our problem. Misuse is not ours. IMHO.

No, it is our problem. We can't just create whatever and throw it over
the fence. The properly designed API has to make correct use very easy
and incorrect use very hard. That's the point of designing the API, not
just giving people means to run random pieces of C code from PHP.

With that in mind, the API should be designed so that misuse -
especially unintentional misuse - is hard. Not impossible - that we
can't do - but hard. It *is* our responsibility.

Please be aware that the use case you are currently considering -
whatever it is, does not matter - is about 0.001% of all use cases, or
less. Just because PHP runs on millions of sites with wildly different
requirements. So we should support big sites, small sites, slow sites,
fast sites, etc.
