-// TestSimpleTaskRunner is a simple TaskRunner implementation that can
-// be used for testing.  It implements SingleThreadTaskRunner as that
-// interface implements SequencedTaskRunner, which in turn implements
-// TaskRunner, so TestSimpleTaskRunner can be passed in to a function
-// that accepts any *TaskRunner object.
-//
-// TestSimpleTaskRunner has the following properties which make it simple:
-//
-//   - It is non-thread safe; all member functions must be called on
-//     the same thread.
-//   - Tasks are simply stored in a queue in FIFO order, ignoring delay
-//     and nestability.
-//   - Tasks aren't guaranteed to be destroyed immediately after
-//     they're run.
-//
-// However, TestSimpleTaskRunner allows for reentrancy, in that it
-// handles the running of tasks that in turn call back into itself
-// (e.g., to post more tasks).
-//
-// If you need more complicated properties, consider using this class
-// as a template for writing a test TaskRunner implementation using
-// TestPendingTask.
-//
-// Note that, like any TaskRunner, TestSimpleTaskRunner is
-// ref-counted.
