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.

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.
