Hi Erik, I did not notice  slowdowns in our night makes .

Looking at a specific  test machine  I use  (x86_64,  build JOBS hardwired  set 
 to 12 )   I  get around  6 minutes build time  with and without the feature .

( but you have to take into account  that  the  link-time section-gc   on  
x86_64    in my patch is only enabled  for the smaller JDK libs and not 
libjvm.so  )  

Best regards, Matthias
