| src/lib/libc/net/gethostbydns.c seems to use a load of static

Yes, I noticed that as well. I also noticed that gethostbyaddr_r worked
"less" than gethostbyaddr did (the result was that all threads ended up
thrashing each other, and not of them continued on). I was going to use
res_query, but noticed that it too used static buffers (although it looks
pretty easy to fix).
Would anyone be offended if I were to produce a few patches to fix up these
routines once and for all? Should I just produce a few #ifdef _THREAD_SAFEs
or try full blown routines (gethostbyaddr_r, res_query_r)?
Thanks,
Dan
