Of course, there were shared libraries long before Un...I mean
Posix-like-systems...had them:

RSX-11M.
SDS (later XDS) CP-V and its predecessors.
	the above used a fixed-place transfer vector.
Primos V-mode, using name lookup and runtime pointer patching.

People even older than me can no doubt go further back.
