From ab3505360bf6612d18915a39a0fec74b00642e82 Mon Sep 17 00:00:00 2001 From: "atwilson@chromium.org" Date: Fri, 30 Oct 2009 18:11:47 +0000 Subject: Initial pass of shared workers renderer-side code Added initial interface hooks betweek WebKit code and renderer-side worker code. The proper messages are generated to fire off a shared worker, but they are currently ignored by the browser process.
