Wouldn't that cause a rather huge compatibility issue given that the 
current oom_adj works in a totally different way:

! 3.1 /proc/<pid>/oom_adj - Adjust the oom-killer score
! ------------------------------------------------------
! This file can be used to adjust the score used to select which processes
! should be killed in an  out-of-memory  situation.  Giving it a high score
! will increase the likelihood of this process being killed by the
! oom-killer.  Valid values are in the range -16 to +15, plus the special
! value -17, which disables oom-killing altogether for this process.

?

Cheers,
FJP
