A suspended session has been gracefully suspended within the client.

A running session could either be an active one currently used, or one
that is still waiting for a timeout of the client crashed or the
connection was dropped prematurely for any reason.
Running sessions should switch into suspended state after a (rather
long?) timeout.

You cannot attach to running sessions, but you can forcefully suspend a
running session from the client and then attach to it.

Personally, I don't like this behavior. I'll though explain what's going on:

If no session exists on the server, a new one is created and
automatically attached to (well, pretty obvious case.)

If there is a suspended session, there multiple two cases:
  1.) the session you currently want to start matches the already
existing, suspended session (same settings, including the
"application"/"desktop" to start) => this session will then be attached
to without prior notification, you will NOT see the session list beforehand
  2.) the session to start matches a "running" session on the server.
You will be presented with the list (and able to forcefully suspend the
running session, if that's what you're after.)
  3.) the new session differs in session setting details. In this case,
you will get the session list.

I don't like this, because it's inconvenient if you explicitly want to
start a new session with the same characteristics. In my opinion, the
session list should always be provided if one session (no matter the
settings or state) is running on the server.
