Bug 51470 The BuildManager goes into an endless loop running the AutoBuildJob
The AutoBuildJob goes into an enless loop. This is happening when markers are being generated by the builder. The problems view is refreshing which in turn interrupts the AutoBuildJob thus causing the whole cycle to start over. Contact me directly if you need more info or a testcase.
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
