    // Rough approximation of the external storage needed for the hashtable.
    // This isn't exact, but it is close enough, and proportional to the actual
    // external mermory usage.
    visitor.reportExtraMemoryUsage(thisObj->m_map.capacity() * (sizeof(JSObject*) + sizeof(WriteBarrier<Unknown>)));
