Bug 55090 [Progress] How to show busy in multiple instances of the same view
Currently to get the view busy indicator you have to schedule a job in a workbench part. But what happens when there are multiple instances of a view created, which view should be busy. Ideally, you could instead associate a view type with a job.
bundles/org.eclipse.ui.ide/src/org/eclipse/ui/views/markers/internal/MarkerView.java
void updateTitle() {
		String currentTitle = getTitle();
		String viewName = getConfigurationElement().getAttribute("name"); 
		String status = ""; 
		int filteredCount = currentMarkers.getItemCount();
		int totalCount = getTotalMarkers();
		if (filteredCount == totalCount) {
			status = Messages.format("filter.itemsMessage", new Object[] { new Integer(totalCount)}); 
		} else {
			status = Messages.format("filter.matchedMessage", new Object[] { new Integer(filteredCount), new Integer(totalCount)}); 
		}
		String newTitle = Messages.format("view.title", new String[] { viewName, status }); 
		if (!newTitle.equals(currentTitle)) {
			setTitle(newTitle);
		}
	}
	
	/**
	 * Updates the message displayed in the status line.  This method is
	 * invoked in the following cases:
	 * <ul>
	 * <li>when this view is first created</li>
	 * <li>when new elements are added</li>
	 * <li>when something is deleted</li>
	 * <li>when the filters change</li>
	 * </ul>
	 * <p>
	 * By default, this method calls <code>updateStatusMessage(IStructuredSelection)</code>
	 * with the current selection or <code>null</code>.  Classes wishing to override
	 * this functionality, should just override the method
