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.

	 * changes will be scheduled in a background job, and may not take effect
	 * immediately.

	protected void refresh() {
		uiJob.setPriority(Job.INTERACTIVE);
		uiJob.setSystem(true);
	
		if (refreshJob == null) {
			refreshJob = new RestartableJob(
				Messages.format("MarkerView.refreshTitle", new Object[] {getTitle()}),
				new IRunnableWithProgress() {
					public void run(IProgressMonitor monitor) throws InvocationTargetException, InterruptedException {
						internalRefresh(monitor);
					}
				});			
		}
		
		refreshJob.restart();
