+// Worker APIs that run on the IO thread. While we could make it RefCounted,
+// the Worker system is the only place that really needs access on the IO
+// thread. Instead of changing the lifetime semantics of StoragePartition,
+// we just create a parallel struct here to simplify the APIs of various
+// methods in WorkerServiceImpl.
+//
+// This class is effectively a struct, but we make it a class because we want to
+// define copy constructors, assignment operators, and an Equals() function for
+// it which makes it look awkward as a struct.
