You could malloc() a struct hostent for each call to
gethostby*(), each time registering the hostent in some list along with the
thread's PID. If the same thread calls gethostby*, use the same buffer, or
allocate a new one if another thread calls it. Have a static function be called
atexit to free all the mallocs.
