The notes I wrote that were the basis for all HTTP/1.0 implementations
of keep-alive.  You can find them somewhere on the http-wg list.  If used
properly, a client could tune its requests such that leaving a
connection hanging around would never be a server problem.  If not used,
then it is just semantic sugar (good for debugging).  It was dropped
from HTTP/1.1 because Jeff Mogul believed that a server should never
close its connection unless resource constraints were exceeded, and
thus telling the client in advance how many pipelined requests it
could make was no longer deemed "useful".
