i understand there are a lot of progress in threads support in kernel
	side, however, i'm a bit worried about library side.  for instance,
	all resolver libraries are not thread safe.  they are from BIND4,
	and is heavily modified so it is not trivial for us to upgrade to BIND8.
	(for example, nsdispatch directly conflicst with BIND8 irs.conf)
	what are the grand plan?
