    Windows: wait for I/O on buffers to complete in cm_SetupStoreBIOD
    
    cm_SetupStoreBIOD constructs a list of dirty buffers for a file
    that are to be written to the file server.  When constructing
    the list, if when determining the first dirty buffer we come across
    a buffer that is already actively involved in an I/O operation,
    call buf_WaitIO() to wait until the buffer is no longer busy before
    continuing.  This reduces lock contention and synchronization
    conflicts.
