  tail: add an option so that using -f on N files doesn't monopolize
    N file descriptors

  sort: consider Paul Eggert's speedup patch.
  sort: use strcoll for a slow-but-locale-aware mode

BUGS
====

  * join is reported to fail two tests on alpha-based Dec OSF 4.0 systems
    when compiled with the vendor C compiler.  I have no way to determine
    if that is due to a bug in join or a problem with that particular
    compiler.
