New submission from Nick Coghlan <ncogh...@gmail.com>:

As part of the PEP 384 discussion, it was noted that one of the problems with 
mixed C runtimes on Windows is that each C runtime in the process has it's own 
idea of the current locale setting.

This can be addressed to some degree by having extension modules query and 
modify the Python interpreter's locale setting rather than the C runtime 
setting, but doesn't help those modules react to *changes* in the setting.

Would it be worth adding a callback registration mechanism to the locale module 
to allow modules to be notified when the locale changes? (It seems like this 
may be useful even outside the context of PEP 384, e.g. to dynamically update 
displays in GUI applications)
