    Why is it necessary to have a different architecture to run emphemeral
    GC?  Aren't both Suns and Symbolics machines Turing machines? :-)

I refer you to the paper "Garbage Collection in a Large Lisp System" by
David A. Moon, Conference Record of the 1984 ACM Symposium on Lisp and
Functional Programming.  This paper explains how the ephemeral garbage
collector works, and the architectural support it uses to provide
efficient garbage collection without degrading the performance of
regular program execution.
