Have you tried stdout.sync = true ?

--------------------------------------------------------------- IO#sync=
     ios.sync = aBoolean -> aBoolean
------------------------------------------------------------------------
     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)


Hope this helps,

Bill
