    Revert "Use 'xargs -P0' to further improve performance"
    
    This reverts commit 6ab80e88c5742a9de5a943f2742191fba7987cca.
    
    If there are enough hits, the output becomes mixed up (like xargs'
    manual warns). Let's leave up any locking schemes, or whatever, up to
    whoever motivated enough comes next.
