Bug 34040 It takes a minute to expand a project in Package explorer
Build: RC1 For scalability testing, I'm developing against WSADIE. I imported a plug-in whose classpath contains >200 external jar entries. The project is initially collpsed. In the package explorer view, if you click on the + to expand the project, it will take about 60 seconds for the project to expand. After it expanded, I went into the view filters and changed it so that I could see the hidden '.*' files, it will take another minute to update the view.

		if (needsToDelegateGetParent(child)) {
			return fPackageFragmentProvider.getParent(child);

			return super.getParent(child);
	}

			IPackageFragmentRoot root= (IPackageFragmentRoot)element;
			IJavaProject project= root.getJavaProject();

				IClasspathEntry[] entries= project.getRawClasspath();
				for (int i= 0; i < entries.length; i++) {
					IClasspathEntry entry= entries[i];
					if (entry.getEntryKind() == IClasspathEntry.CPE_CONTAINER) {
						if (ClassPathContainer.contains(project, entry, root)) 
							return new ClassPathContainer(project, entry);
