    find: Flush stdout before executing commands
    
    The commands may produce output themselves, so this is required to
    ensure that our -print output is actually written before a command's
    output, and also that we don't end up with partially written lines
    due to stdout buffering intermixed with the output of other commands.
    
    Other implementations of find(1) do the same.
