An unsuccessful call has no synchronizing effect at all.

may be considered to be able to return false
even when the mutex <i>l</i> is unlocked.

The <code>sync</code> package provides a safe mechanism for
initialization in the presence of multiple goroutines
through the use of the <code>Once</code> type.

==== Keystore Password

In FIPS 140-2 mode, the elasticsearch keystore needs to be password protected with a password
of appropriate length. This is handled automatically in `fips.gradle` and the keystore is unlocked
on startup by the test clusters tooling in order to have secure settings available. However, you
might need to take into consideration that the keystore is password-protected with `keystore-password`
