Re: holding connections open: a modest proposal

There is no cpu overhead for idle connections. There is a memory overhead for
the TCP control block, but this is quite small. There is also a slight penalty
through more collisions in the hash table.
However, this TCP control block hangs around for some time after the connection
is closed, still taking up resources- one per connection. Thus the breakeven
point for memory use occurs when the average time between transactions is
greater than 2MSL.
