    // We need to lock all the mutexes to reset everything to cause it to be
    // reloaded, but whenever we lock individual members we should always do it
    // in the same order (well, the same order*ing* not necessarily the same
    // order) to avoid deadlocks.  This means that we need to enumerate the
    // finicky, implicit dependency order that we have due to each member's
    // constructor referencing root recursively.  We could avoid doing this
    // explicitly with C++11's std::lock (if c++11 threading primitives were
    // finally reliable on all targets), or some other equivalent deadlock
    // avoidance algorithm.
