AIX is an IBM-only sort of OS isn't it?
I believe so but then again, you didn't ask the question as "is there a such a thing for ALL UNIX". And I only answered the simple question of "is there such a thing" - I didn't answer the complications of it being used in certain/all environments.
But, if a thing exist and is useful, others will copy it at some point. It's possible some other Linux or UNIX has this feature - let's see if others respond with more knowledge.
