I've added a note to the PHP website page for gettext:
http://www.php.net/manual/en/ref.gettext.php
===============================================================
Make sure you check your webserver configuration before deciding
to use gettext, because if you are running in a multi-threaded
environment you should not use gettext, as it is not thread-safe.

A future version of gettext(possibly 0.15) may be thread-safe.
Any gettext dependencies, such as glibc would also need to be
thread-safe.

Apache 1.3 on Unix generally is non-threaded, but on Windows it
is multithreaded.
Apache 2.0 has support for MPMs(Multi-Processing Modules), some of
which support multiple threads:
