--- Comment #2 from Michael Catanzaro <mcatanzaro at gnome.org> ---
Somebody else noticed this changed in bug #242690. Before, isMainThread() only checked to ensure the current thread is the same as the thread that first called initializeMainThread(); i.e. it was possible for WebKit's main thread to not be the actual main thread. Now, isMainThread() checks to ensure it is actually the main thread.

In theory, using a secondary thread as the "main" thread *might* have previously been safe to do as long as you restrict all use of WebKitGTK and GTK and <who knows how many other libraries> to only that thread. In practice, probably not a good idea. I'd say Eclipse should not do this.

Maybe we should have not backported this change to the stable branch, though. It's nicer when things break in major version updates instead of minor updates.
