Bug or feature? std.c.stdlib.exit() breaks RAII

[Ashish Myles]

std.c.stdlib.exit() seems to break RAII. The code below tests this
both using a struct destructor and an explicit scope(exit) {}.  Is
this an intentional feature or a bug?

import std.stdio;
import std.c.stdlib;

void main()
{
    struct SafeExit {
        ~this() {
            writeln("Safely exit with destructor.");
        }
    }
    SafeExit safeExit;

    scope(exit) { writeln("Safely exit with scope(exit)."); }
    scope(failure) { writeln("Safely exit with scope(failure)."); }

    writeln("Test if std.c.stdlib.exit() breaks RAII.");
    writeln("Pre-exit!");
    std.c.stdlib.exit(0);
    writeln("Post-exit! Should not get here!");
}
