Stopping double clicking with Perl CGI

[Paul Makepeace]

Off the top of my head,

<button id="onetime" onclick="javascript:disable();">Click me!</button>

<script type="text/javascript">
function disable() {
  var button = document.getElementById('onetime');
  button.disabled = true;
}
</script>

I could use semaphores server side or do a radical architecture change to some sort of queued system but this seems overkill. In fact all of this seems overkill for what must really be a common problem requiring a mundane solution.
