A solution to this problem is in Pen 0.8.0, which has separate soft and
hard limits on the number of connections to each server. If you previously
invoked pen as:
pen 80 server1:80:100 server2:80:100
you can now do
pen 80 server1:80:90:100 server2:80:90:100
This will cause the last 10 connections to be reserved for clients that
have used this server before.
The syntax is address:port:soft:hard. If the hard limit is omitted, it is
effectively the same as the soft limit.
