I am running putty via a SOCKS5 proxy (without authentication) with a single dynamic forwarded port.

I then run Deluge and configure all 4 the proxy settings with SOCKS5, 127.0.0.1 and the above forwarded port.

I see putty memory utilization constantly increasing:-

$ ps aux | egrep -i "putty|mem"
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
jon 7419 0.6 1.0 7424 5208 ? S 12:24 0:27 putty
$ ps aux | egrep -i "putty|mem"
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
jon 7419 0.6 1.0 7564 5252 ? S 12:24 0:30 putty
$ ps aux | egrep -i "putty|mem"
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
jon 7419 0.6 1.0 7696 5348 ? S 12:24 0:34 putty

It was up to 80+ Meg before I restarted it!
