There is some more shardware/software out there which has problems
if two DNS requests are sent using the same tuple
(source addr, source port, dest addr, dest port)
This can range from firewalls to load balancers. Some of the vendors
already fixed it in response to this problem. Still, we need a way
to make glibc work with broken environments. The single-request-reopen
flag can be used or we fall back automatically to this mode.
* resolv/res_init.c (res_setoptions): Recognize single-request option.
* resolv/res_send.c (send_dg): If we sent two requests at once and
only get one reply before timeout switch to mode where we send the
second request only after the first answer has been received.
ESRCH return value.

* resolv/res_init.c (__res_vinit): Initialize nscount to zero.
* sysdeps/posix/getaddrinfo.c (gaih_inet): In case we use

the no_data variable.
