A Candidate Recommendation for Web Workers has been published and as
such, this is a Call for Implementations of the CR:
<http://www.w3.org/TR/2012/CR-workers-20120501/>
The root of the spec's test mirror is:
<http://test.w3.org/webapps/Workers/tests/>.
CanIUse reports relatively broad deployment of the Worker interface
<http://caniuse.com/#feat=webworkers> but less so for SharedWorkers
<http://caniuse.com/#feat=sharedworkers>.
(I will issue a separate call for tests on the public-webapps-testsuite
list.)
