Patch Set 1:

Matthias, I work for IBM, a member company, is a CQ still required? I thought I saw some SAP code slip by after Chris/Gunnar gave the PMC approval? :O

As for the "derived" problem, my IResourceVisitor _is_ checking via Team.isIgnoredHint(IResource) so I'm not quite sure what's going on here. I'll have to investigate some more with some breakpoints.

Anyway, I can see why it might take a while if it's doing a full walk but I'm surprised to hear that the 'Send to Background' button was disabled. Do you remember what the progress monitor was saying?
