Doesn't it currently just launch the process under the calling user account?

Currently - yes but it is not fully implemented yet. I'd like to avoid renaming
the class and files later when this change happens.

+class UnprivilegedProcessDelegate : public WorkerProcessLauncher::Delegate {
+ public:
+  UnprivilegedProcessDelegate(
+      scoped_refptr<base::SingleThreadTaskRunner> main_task_runner,
+      scoped_refptr<base::SingleThreadTaskRunner> io_task_runner,
+      const FilePath& binary_path);
+  ~UnprivilegedProcessDelegate();

nit: virtual

[alexeypa (please no reviews), 2012/10/09 19:42:04]

Done.
