hi Serkan,
      At the moment we are enabling multi-threaded self-heal for only 
replicate volumes, mainly because we didn't get enough time to test the 
changes with disperse volumes. Do you want to help out with testing 
multi-threaded heal in disperse volumes? I can provide a patch which 
does this. We can may be target this for 3.7.13 based on your inputs?
