In cases where one wants to produce a system image with a lot of locales supported (e.g. supporting a number of collations for user selection in various programs), it's easiest to generate a ton of locales. However, it's easily the slowest step of such a image/debootstrap, by a rather lot.

It looks like Arch Linux has both inherited locale-gen and decided to patch it up to support parallel execution, some speed gains, so there's some prior art here:
