The 'bindtextdomain' function is multi-thread safe and idempotent.
Therefore the libfoo_initialize function [1] is multi-thread safe and
idempotent as well. That is, in the case that multiple threads call
create_foo at the same time, libfoo_initialize may be called several
times, but this is harmless.

No?
