Yes, as i said it in earlier threads, lacking other in-tree use, 
utrace is only acceptable for upstream if it materially cleans up 
the ptrace code here and now - without any wide #ifdefs like some of 
the earlier patches did.

The latest patches from Oleg clearly go in this direction, which is 
a very promising development!
