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.
