    Windows: cm_GetNewSCache drop lock to permit change
    
    In cm_GetNewSCache the entire LRU queue is searched for a
    cm_scache_t object that is safe to recycle.  If none are the LRU
    queue was immediately searched again without dropping the
    cm_scacheLock or taking a pause.  As a result it is quite possible
    that a thread about to release a cm_scache_t was blocked from
    doing so.
    
    This patchset factors some of the logic a bit differently to
    improve readability and adds new log messages to help diagnose
    the cause of a problem if no cm_scache_t ever becomes available.
