And to answer my own original question... :-)

Someone from UNIX System Laboratories returned my call and explained
the situation with SVR4.  No, SVR4 does not have any form of
asynchronous I/O.  A pre-release version did exist, but it was
removed from the distributed code.  Some of the STREAMS functionality
depends on definitions in the asynch header files, so they had to stay.
