I have two problems with this approach:
  * it requires enough disk space to temporarily hold two copies of
    the log, which can sometimes be a problem
  * it can loose some log information (that written between the
    "cp" seeing EOF and the creat() call of the ">"); on lightly
    loaded systems this is not likely to be too much of a problem,
    but on a heavily loaded system this could potentially loose
    a few transactions
