    Windows: avoid race in cm_GetNewSCache
    
    The cm_scacheLock is dropped while walking the scache LRU queue.
    As a result it is possible for the cm_scache_t that is being
    considered for recycling to be accessed and moved to the head
    of the queue.
    
    Track the prev and next pointers so it is possible to detect if
    the cm_scache_t that is about to be recycled has been moved.  If
    so, restart the search from the tail.
