    As dwalin suggested, showing up in the pageant menu would be great.
    Alternatively, a new entry in the tray with its own menu would be
    okay.

    By way of context, I've been using OpenSSH with ssh-agent and ssh
    tunnelling started from a Cygwin bash window, and shutting them down
    using kill in Cygwin. However, my latest Cygwin upgrade doesn't let
    me detach them from the Cygwin window and creates zombie windows if I
    forget and exit before shutting down the processes. This motivated me
    to switch to PuTTY; I like the switch so far.

    There's always Ctrl-Alt-Del and End Process, but something slightly
    more friendly would be nice.
