Recursive setinterval calls a no no in JS.
This is from a page on PHP that used a JS setInterval recursive in their
API, had to disable it.

It uses the javascript setinterval function to call itself every 50 ms.
However, it overwhelms netscape 4.X garbage collection and causes memory to
start being eaten at a rate of 1 k per second. When we rolled out our stuff
at CSG, it took machines down after 1/2 hour. I fixed most of the problem
by commenting out the setinterval, but then you lose some functionality.
It's a great idea, but Netscape is holding us back.
So, I rewrote our code to do what we needed to in two different JS files.
