As Emacs' `(beep)' does not work on Kubuntu 10.10, my .emacs contains

  (setq ring-bell-function
	(lambda ()
	  (call-process "beep" nil 0 nil "-f" "400" "-l" "100")))

Although the `beep' executable is as lightweight as it can possibly be,
the results are far from perfect. For instance

(beep)
(sit-for 0.1)
(beep)

usually makes two audible beeps, but often only one beep is
perceived. On the machines where Emacs' (beep) works, there is no such
problem.
