Hi!

One of them has to do with number formatting, so if you have a number of
apps that use different locale settings on the same server, which have
different number separators, you may encounter it. Not a frequent use
case, though. See: http://bugs.icu-project.org/trac/ticket/6711
Not unique to TS, but there might be ones that are, if they use globals
in this manner. Just showing that modern libraries are still having this
kind of issues, and it's very hard to get maintainers to fix them.

ITYM based or processes, or s/none/all/. But so what? For IIS case
threads are fine, but for our case - shared-nothing - they don't help us
much. No idea what asp.net does but they probably designed it to be
threaded from scratch, so it probably has very different architecture
than PHP.

AFAIR all APIs that go into filesystem, C library, etc. ultimately end
up with Unicode - i.e.

TLS is nice, I have nothing against TLS, and if somebody wants to get
behind the effort to get ZTS to use TLS, great. But I was talking about
cost of setting up envt for PHP script, which is not going to change.
You need to initialize all the globals, create all the structures, etc.
etc. - it's all not free.

> The IIS pipeline architecture allows much more than only auth, much more.

I know, it's just an example. I'm just saying PHP request init is
expensive, and I'm not even sure we can do proper init on early stages
of IIS request... So PHP may not be the best thing to use inside IIS
pipeline in general case.

Fine, so who's going to do this? This RFC is marked with 2008, now it's
2013 and it didn't happen. Why?
