[jQuery] How to implement prototypes PeriodicalExecuter in jQuery

[Urkman]

Hello,

I was using prototype for several years.
Now I want to completly change to jQuery.

One left problem is, that I need an equivalent to prototype's
PeriodicalExecuter.
How can I do the following with jQuery?

#####
//click "start button"
$myPeriodicalExecuter = new PeriodicalExecuter
(myPeriodicalExecutedFunction, 3);

//click "stop button"
$myPeriodicalExecuter.stop();

function myPeriodicalExecutedFunction() {
  //do someting
}
#####

Thanks for your help
