My memory of this is it was dns lookups that wanted something like this.
SunOS really wanted the world to love YP but the world wanted Sun to
support DNS. You could, and people did, make a shared lib that overloaded
the default gethostbyname(3) that wanted to do YP, the lib would provide
a DNS based one instead.
That's where I first learned of this stuff. Gingell would know if you
want to know for sure.

symbol preemption
yes, but unless my memory is playing tricks, SunOS a.out had this
feature.
Do you mean support for shared libraries, or symbol preemption?
