Threads on HP-UX 10.x are implemented in user-space. Although
gethostbyname_r() is reentrant, maybe the underlying DNS resolver,
which resides in kernel-space, is not multi-thread safe per default?

Gilles, I would like to suggest that you check the documentation
on your compiler about how multi-threaded applications should be
compiled -- maybe a special option is needed, or you have to link
with a special version of libc (or wherever the DNS resolver is
located).
