How about the following solution? Beautiful, isn't it? ;-)

Hope it helps,
Gennady.

P.S. And seriously, where's the code that does not work? As a not so wild guess, you use a class method instead of the instance one.

--------------------------------------------------------------- IO#sync=
     ios.sync = boolean   => boolean
------------------------------------------------------------------------
     Sets the ``sync mode'' to true or false. When sync mode is true, 
     all output is immediately flushed to the underlying operating 
     system and is not buffered internally. Returns the new state. See 
     also IO#fsync.

        f = File.new("testfile")
        f.sync = true

     (produces no output)
