[PATCH] Threadsafe locale initialization

[Benjamin Kosnik]

Hi Pétur.

I like this patch very much, and consider this a necessary first step
for the detangling of the object files.

Nice.

Here's a slightly modified version of this patch. I've tested it 

x86/linux
x86/linux --enable-clocale=generic
x86/linux --disable-threads

etc etc.

Seems fine.

Loren, any thoughts?
