Last I checked, dzen didn't have a way to remove itself after a timeout; if
you want to do that, or you otherwise want to manipulate the window (say,
update or remove and post a new one of the user immediately changes
workspaces again), it's far easier to create it internally and pass the XID
around than it is to try to find/save the XID via the ManageHook.
 Especially if you don't want the window to be managed otherwise.  (Note
that, for the same reason you can't tell apps to start on a specific
workspace directly, you can't get an XID out of spawning an application; it
isn't known until the window is created, and not identifiable as belonging
to a particular application until the window is actually mapped, and the
ManageHook will receive it at that point.)
