+/**
+ * An extension to the IProgressMonitor interface for monitors that want to
+ * support feedback when an activity is blocked due to concurrent activity in
+ * another thread.
+ * <p>
+ * When a monitor that supports this extension is passed to an operation, the
+ * operation should call <code>setBlocked</code> whenever it knows that it
+ * must wait for a lock that is currently held by another thread. The operation
+ * should continue to check for and respond to cancelation requests while
+ * blocked. When the operation is no longer blocked, it must call <code>clearBlocked</code>
+ * to clear the blocked state.
+ * <p>
+ * This interface can be used without OSGi running.
+ * </p><p>
+ * Clients may implement this interface.
+ * </p>
+ * @see IProgressMonitor
