Till now I could use Boost.Locale without dependencies on Thread when
it was working without ICU. It is not a problem to add a dependency.

I just thought if there is a some kind of lightweight mutex that can be
used without boost.thread? I can bring something on my own (it is really
20 lines of code) just maybe there is something ready for roll...

If not I'll add dependency on system.

No, it there is not other problems.
