Hello, thank you for your time for Corkscrew development. Very useful tool. Seems, that I found a small bug. Corkscrew eats 100% of CPU when ssh server unavailable by network problems. There is happens when I receive similar error message from proxy server: Gateway Timeout ssh_exchange_identification: Connection closed by remote host

Seems that corkscrew trys reconnecting without any pause, causing proxy flood.

$ corkscrew --help corkscrew 2.0 (agroman@agroman.net) From official repositoies of Ubuntu 18.04

I've checked the least version from master. Problem the same.

Check PR!14. They did mention your problem, so it might already be fixed there.

Occasionally, Corkscrew uses 100% of my CPU capacity. Can someone help resolve this issue as it's causing significant damage to my PC?
