I agree that deleting the .po files probably won't impact your physical

This might not be entirely true.  Gconf does now separate locale 
specific strings into separate backend files.   But fonts for all 
locales tend to be loaded regardless of your base locale. 

For example, launching eog in the "C" locale (Solaris Nevada build 82, 
GNOME 2.20.2)  opens font files for many other locales.  These may be 
mapped into physical memory at times, regardless of your locale. :

This might make sense for a browser or email client, but if there is a 
performance and memory impact, it would be nice to have the option to 
disable loading of fonts from other locales.  Some GNOME users are 
running on thin client kiosks on isolated networks (banks...) where they 
are unlikely to need all of these fonts.
