My knowledge here gets thinner... again, what I know:
I am told by IBM people that AIX runs a 'kproc' task for every AIO request. It does not show in normal 'ps' output (have to use UCB style 'ps') and looks like a "k"ernel "proc"ess.
Sun boasted improved performance with KAIO in Solaris 2.4, more or less at the same time when they modularized telnetd and ran that in kernel as well.
