[benm at omega corlib]$ find -name \*.cs | xargs grep Locale.GetText | wc -l
712
[benm at omega corlib]$ find -name \*.cs | xargs grep Locale.GetText | grep -v Exception | wc -l
194

Most of those 194 seem to be cases where Locale was put on a different
line than the throw statement for cosmetic reasons.

The best way for Kornel to do that (just as an FYI since he has probably
never used the tools) is to run:

mono --stats foo.exe
mono --profile foo.exe

where `foo.exe' is a program that exercises the Locale code, but doesn't
do much else, and send the output for each before and after the change.
