/** In the current POSIX.1 specification (POSIX.1-2008), readdir() is not required to be thread-safe. However, in modern
* implementations (including the glibc implementation), concurrent calls to readdir() that specify different directory streams
* are thread-safe. In cases where multiple threads must read from the same directory stream, using readdir() with external
* synchronization is still preferable to the use of the deprecated readdir_r(3) function. It is expected that a future
* version of POSIX.1 will require that readdir() be thread-safe when concurrently employed on different directory streams.
