commit 7686880191a159352874c86d95b4fcabc446b778

    Windows: buf_CleanVnode avoid lock contention
    
    In the middle of the big loop do not obtain buf_globalLock unless
    cm_buf.qFlags & CM_BUF_QREDIR is non-zero.  buf_globalLock is heavily
    contested and any reduction in contention is an improvement.
    CM_BUF_QREDIR is never set when 'cm_directIO' is true (now the default)
    so this is a huge win.
