i don't think this is the problem that chuck is referring to.
afaiu, it's rather that the two processes need to have a priori 
knowledge of two different "thingies" in order to share some memory 
(without bad surprises): the ID and the size.

from a UX pov the question is, why it's not possible to only have to 
share a single "thingy" (the ID) and have the others be shared implicitly.
