Note that if there are no read-write or write-write data races on memory location <i>x</i>,
then any read <i>r</i> on <i>x</i> has only one possible <i>W</i>(<i>r</i>):
the single <i>w</i> that immediately precedes it in the happens before order.

More generally, it can be shown that any Go program that is data-race-free,

	if cannotHeal && quorumETag != "" {
		// This is an object that is supposed to be removed by the dangling code
		// but we noticed that ETag is the same for all objects, let's give it a shot
		cannotHeal = false
	}

	if !latestMeta.Deleted && !latestMeta.IsRemote() {
		// check if there is a part that lost its quorum
		for _, partErrs := range dataErrsByPart {

  elif is_windows():
    default_cc_opt_flags = '/arch:AVX'
  else:
    # On all other platforms, no longer use `-march=native` as this can result
    # in instructions that are too modern being generated. Users that want
    # maximum performance should compile TF in their environment and can pass
    # `-march=native` there.

# Recipes

We've written some recipes that demonstrate how to solve common problems with OkHttp. Read through them to learn about how everything works together. Cut-and-paste these examples freely; that's what they're for.

 * pool's daemon thread may not exit immediately.

 * ```java
 * client.connectionPool().evictAll();

 * If your client has a cache, call [close()][Cache.close]. Note that it is an error to create calls
 * against a cache that is closed, and doing so will cause the call to crash.

  // in the short hash. We saw that a mask of 0x7f would keep the 7-bit value 0x6f from a full
  // hashcode of 0x89abcdef. The imaginary `hash` value would then be the remaining top 25 bits,
  // 0x89abcd80. To this is added (or'd) the `next` value, which is an index within `entries`
  // (and therefore within `keys` and `values`) of another entry that has the same short hash

- e2e tests that require SSH may now be used against clusters that have nodes without external IP addresses by setting the environment variable `KUBE_SSH_BASTION` to the `host:port` of a machine that is allowed to SSH to those nodes.  The same private key that the test would use is used for the bastion host.  The test connects to the bastion and then tunnels another SSH connection to...
