ok, like 4 months later ... but this is really bugging me and i can't
seem to get it working no matter what options i try.

i have `cache=loose` enabled, but `locale-gen` still fails, albeit
with a different error:

# locale-gen
--------------------------------------------------------
Generating locales...
  en_US.UTF-8...cannot change mode of new locale archive: No such file
or directory
--------------------------------------------------------

... so now the mmap is working, and the `ln` supposedly works, but the
file is missing(?):

# strace -ff -s256 -e trace=file,desc locale-gen
--------------------------------------------------------

... what is going on here?  it's like the descriptor magically
disappears ... ideas?  everytime there is glibc update, i must chroot
from the host and regenerate the botched locales.

host and guest are both Archlinux, kernel 3.4.4.  addtl details follow ...
