Re: [Request] How about adding with-locale?

[Nala Ginrut]

According to our talking on IRC. I dropped locale specific procedure setlocale in my code. I choose (web http) write-date instead. 
And my conclusion is to avoid locale specific things in multi-thread context. Writing a new procedure for the same
issue is a better solution.

No, that wouldn't work.  For one thing, what if the body of
'with-locale' takes a long time?  Also, consider this:

 Thread 1: (with-locale "foo" (strftime ...))
 Thread 2: (format ...)

If the 'format' and the 'strftime' happen simultaneously, then 'format'
will use the "foo" locale, which is incorrect.

During 'with-locale', we would have to prevent other threads from doing
_any_ locale-dependent operation.  In a system like Guile, where a
process may contain arbitrary C code and shared libraries, there's no
sane way for us to do this.  In any case, it would not scale well.
