Subject: thread safer libc (note: safer, not safe) Access to the global _res
 structure replaced by pointers to a per thread instance.  If unthreaded the
 pointer is to the global structure.

Also replaced a 64k stack array with malloc-ed memory so
threaded aps (with a default 64k stack) have a chance at working.
