 Double-checked locking is easy to mess up. If you really need to write your own double-checked locking, in spite of the rules [CP.110: Do not write your own double-checked locking for initialization](#Rconc-double) and [CP.100: Don't use lock-free programming unless you absolutely have to](#Rconc-lockfree), then do it in a conventional pattern.
 
-The uses of double-checked locking pattern that are not in violation of [CP.110: Do not write your own double-checked locking for initialization](#Rconc-double) arise when a non-thread-safe action is both hard and rare, and there exists a fast thread-safe test that can be used to guarantees that the action is not needed, but cannot be used to guarantee the converse.

 Some implementations offer vendor extensions like `#pragma once` as alternative to include guards.
 It is not standard and it is not portable.  It injects the hosting machine's filesystem semantics
 into your program, in addition to locking you down to a vendor.
