You nailed it. https://bugs.eclipse.org/bugs/show_bug.cgi?id=544005

An aggregator with 180 tycho built modules is several minutes faster now 
due to that change. Every eclipse project will experience this 
improvement with Tycho 1.4.

Thanks to Thomas.


PS: I also tried the Pathfilter change, but could not measure any 
difference beyond the rewriteParents improvement.
