	Indeed.  glibc has them in same chunk, which did lead to
	different treatment of things -> strange heap corruption.

	There exists configuration option:

	That is *principally* for cases where system libc implementation
	of getaddrinfo() leaves something to desire -- glibc 2.2 might
	not need it, but anything before it likely needs it.
	( There are questionable error processings in the resolver code
	  in the glibc 2.1 )
	BSD might not need it - but might also tolerate its use.
