So select was a great thing until interactive graphics came along.  Just
got too messy.  I recall writing assembly language code to support threads
in the mid to late 1980s, and I remember reading some papers from Sun about
the same.  Everybody was doing it.  Anybody have enough of the history to
paint a picture of how we got from there to standardized threads?
