+
+ new-run-webkit-tests: minor cleanup for multiprocessing work
+
+ This change:
+ * moves worker naming into TestShellThread, eliminating a
+ parameter to the constructor and putting the responsibility in
+ the correct place.
+ * eliminates the _WorkerState() class in message_broker, because
+ it turns out that state really needs to be in run_webkit_tests
+ * renames the Broker classes to be module-private.
+ * fixes a bunch of minor commenting and whitespace issues to
+ make subsequent patches a bit clearer.
+ * Adds a Port hook for default_worker_model() so that we can
+ accomodate the potential for different worker models on
+ different ports.
+ * merge in the fix from 50420 for the brokenness introduced in
+ bug 50367.
+
+ This patch depends on bug 50367.
