The new test (from CL 31468) fails on at least some Linux systems. The Plan 9 version of this bug is #17568.

This is on current tip (go version devel +31f50643c36b Wed Oct 26 22:35:07 2016 +0000 linux/amd64), using the cgo resolver (glibc-2.24-3.fc25.x86_64, i.e. 2.24 plus whatever patches Fedora adds to it).

Output of go test -run=NonLDH net:

=== RUN   TestLookupNonLDH
--- FAIL: TestLookupNonLDH (0.00s)
    lookup_test.go:734: lookup error = lookup !!!.###.bogus..domain.: No address associated with hostname, want no such host
FAIL
FAIL    net 0.004s

And indeed, the test receives EAI_NODATA/-5 from gai:

getaddrinfo("!!!.###.bogus..domain.", nil, 0xc42007d0e0, 0xc42009e098) = -5
gai_strerror(-5)                                                       = "No address associated with hostn"...

How do we deal with it?
