except SunOS only

Calculates ignored users at runtime by extracting them from
passwd database and considering all users with UID < 100
(on Solaris systems) or UID < 500 (everywhere else).

By my timings, this doesn't make it any noticably slower.

-In both cases the tmux server will be started and a background session
-named _prezto_ will be created if a session doesn't already exist.

-By default every shell shares a set of windows but has an independent
-view. Detaching from one of these sessions removes the view but the
-open windows persist. This is accomplished by setting the
-`destroy-unattached` option to `on` for each session.
-
-Some users prefer that all new shells share the same session so that
-the view for each shell is in sync. This useful for advanced users
-that create multiple sessions and want to manually navigate between
-them. To accomplish this behavior set the `mode` option to `shared` in

-You can customize the background session by creating a new session in
-your `.tmux.conf` file.
+In both cases, it will create a background session named _#Prezto_ and attach
+every new shell to it.
 
+To avoid keeping open sessions, this module sets `destroy-unattached off` on
+the background session and `destroy-unattached on` on every other session
