Your example works here, that's why I am asking. But it doesn't work
with Ron's fix. Will look more into it.

For functions that have thread-safe versions in your system, you can
replace the ones used by LuaSocket with the thread-safe ones (man
gethostbyname_r and see what happens). For those that don't, you have to
use a global mutex and lock/unlock around it.

Let me know what you find out.
