The original branch point for this thread was talking about
denial-of-service attacks, such as sucking up too much CPU.  To Sun's
credit, near the bottom of the linked page they plainly say that Java's
protection against DOS is "weak"; heck, they even list 5 specific ways Java
applets can render host machines unusable, and it doesn't take much
imagination to dream up many more.

I don't expect JavaScript/ECMAScript is any better in this respect.  For
that matter, I'm having a hard time imagining a *usable* programming
language that could be.
