Just for your information, it turns out that --enable-vnc-thread is the 
culprit, see

  https://bugzilla.novell.com/show_bug.cgi?id=671809

The method explained there (comment 4) also makes a 0.14.0 compiled from the 
sources and configured as

  ./configure --target-list=x86_64-softmmu \
              --enable-io-thread --enable-vnc-thread

grow.
