Linux, too, has the issue of having to check that addresses that a caller 
passes are actually accessible by them, in relevant system calls. And 
unlike VMS, it has to deal with that issue across something like 2 dozen 
different processor architectures, at current count.

Maybe look at how that deals with it?

Or, like I said, avoid the issue by letting Linux deal with it.
