Darwin also provides an suser(), but it carries caveats:

1- It is not implemented as a wrapper around KAUTH_GENERIC_ISSUSER

2- It is marked as "going away".

Also note that the Darwin KAUTH_GENERIC_ISSUSER does NOT take the  
accounting flags argument, and thus does not set ASU.  I think we  
should try to stick to the Darwin KPI as much as possible, so I think  
we should also skip the accounting flags argument for  
KAUTH_GENERIC_ISSUSER.  If we still want to set ASU, then we need to  
find another way to do it.

Yes, I think we should keep as close to Darwin's KPI as possible, in  
this regard.

(Note, they did something different for the vnode scope [which we  
don't have yet], naming it vnode_authorize(), sigh...)
