Not saying that it's not a good idea (I'd view it akin to locking for
threads, just less generally useful), but what on earth does that have
to do with ECMAScript? ECMAScript doesn't deal with documents,
browsers, laying them out visually or drawing them. The browser is
just one of numerous possible host environments. The specifications
that deal with the browser host in particular are the DOM ones. The
W3C WebAPI group seems to have control over most of DOM specs (SVG
DOM, HTML DOM and similar aside), that's probably a better place to
ask for this.
