But sometimes it's not the easiest thing to trust upstream to do what's
right when bugs that affect all distros go unfixed for years.  e.g.

[john at dsv03-pv1 ~]$ echo $LANG
en_GB.UTF-8
[john at dsv03-pv1 ~]$ time grep '^....' /usr/share/dict/words >/dev/null

real 9m29.275s
user 9m29.055s
sys 0m0.043s

And it pegs my CPU at 100%.   Compare this to...

[john at dsv03-pv1 ~]$ export LANG=C
[john at dsv03-pv1 ~]$ time grep '^....' /usr/share/dict/words >/dev/null

real 0m0.116s
user 0m0.107s
sys 0m0.006s


This little gem has been hanging around since 2005 (
