Some common patterns that mix atomic and non-atomic access are:

* Read-mostly variables where updates are protected by a lock. Within
  the locked region, reads do not need to be atomic, but the write
  does. Outside the locked region, reads need to be atomic.

* Reads that only happen during STW, where no writes can happen during
  STW, do not need to be atomic.

listed in /etc/resolv.conf, or it can use a cgo-based resolver that calls C
library routines such as getaddrinfo and getnameinfo.

On Unix the pure Go resolver is preferred over the cgo resolver, because a blocked DNS
request consumes only a goroutine, while a blocked C call consumes an operating system thread.
When cgo is available, the cgo-based resolver is used instead under a variety of
conditions: on systems that do not let programs make direct DNS requests (OS X),
