Hi,

when I have to go through a proxy host, for example by using the
famous -o "proxycommand jumphost nc %h %p", I might run into a
connection rate limit on the jumphost when I mssh to many hosts
through the same jump host.

This might be mitigated by having a configuration option like "only
connect to X hosts in Y seconds", resulting in "open X connections
simultaneously, sleep Y seconds, open the  next X connections, sleep
again, repeat".

Greetings
Marc
