1179871 - Busy Web Workers should not make the chrome UI unresponsive

Status: RESOLVED DUPLICATE of bug 1300658

(Core :: DOM: Workers, defect, P5)

Description

[(not reading bugmail) Nick Desaulniers [:\n]]

From the Worker Spec [0], there's a demo page [1] that makes FF completely unresponsive [1].  The worker is running [2]:

var n = 1;
search: while (true) {
  n += 1;
  for (var i = 2; i <= Math.sqrt(n); i += 1)
    if (n % i == 0)
     continue search;
  // found a prime!
  postMessage(n);
}
