:mrdocs:

Create a guard object that conditionally manages the specified `lock`, and acquires the lock on `lock` by invoking its `lock` method. The behavior is undefined unless the calling thread does not already hold the lock on `lock`. Note that deadlock may result if a guard is created for `lock` while the calling thread holds the lock on `lock`. Also note that `lock` must remain valid throughout the lifetime of this guard, or until `release` is called.
