I think this might actually be a problem.  A while back I was running a
server w/ rather high load, a fast processor, and limited memory.  I
wanted keepalive timeouts to be around 3 seconds; in fact, if they were as
slow as 5 seconds, better performance could be had by turning them off. 
So, if I understand this correctly, it could significantly affect some
sites, as keepalives are definitely a nice feature.
