Description Roland Schulz CLA 2010-12-09 02:51:34 EST 
Build is relative slow. With the Eclipse Java process constantly using one full core (100% CPU usage in top). 

The yourkit profiler shows that almost all time is spent in:
org.eclipse.cdt.internal.core.ProcessClosure$ReaderThread.run()

This is under Linux running the x86-64 version. It is a cmake project with GCC compiler.
