The lockd implementation for Solaris has been completely re-written from
scratch in Solaris 2.5 by a long-time friend of mine, David Robinson at Sun.
I've known David for over 10 years and he has experience with Suns going back
to the Sun-1. Questions about the details of Sun's implementation of the
locking stuff should probably go to him, at David.Robinson@Eng.Sun.COM.
