I think we'll need a bug report to document the change and the reasons 
behind it (perhaps a copy of the thread where this was discussed with 

Also, is it worth saving the original locale value in msSetup() and 
restoring it in msCleanup()? I realize that in most cases this won't be 
of any use, but I thought I would bring up the idea anyway.

Finally, a note about this should probably be added to the MapScript 
docs (SWIG and PHP docs) since this can potentially cause side-effects 
in scripting environments. I can take care of the PHP docs once the 
change is done.
