    fflush(stdout) to print line by line if stdout is not a tty
    
    To reproduce the issue:
            $ slstatus -s | tee
    
    then it would print only when the stdout buffer is full, by block
    of multiple lines.
    
    fflush() makes sure the line is printed at every loop iteration
