* disabled, as we need to perform slightly different actions.
* Basically the issue here is that the Javascript engine in modern browsers don't
* appear to allow the rendering engine to update the display while it is still executing
* it's thread (well - it does but only after long intervals). This means that the
* 'processing' display doesn't appear for a table sort. To break the js thread up a bit
* I force an execution break by using setTimeout - but this breaks the expected
* thread continuation for the end-developer's point of view (their code would execute
* too early), so we only do it when we absolutely have to.
