Though I guess either way, you have essentially zero chance of getting

Actually as long as you aren't forking/execing a new process,
libstartup-notification isn't really needed anymore -- or soon won't
be (see e.g. bug 347375).  The EWMH, gtk+, and metacity have been
extended a bit so that libstartup-notification is only really needed
for launching processes (and special apps like metacity and
wnck-applet) these days.  Of course, if you have a single instance app
or open windows in response to messages from other applications then
you still have work to do, it's just been reduced...

Also important to libdbus human-readability is the bus name the app
owns, so it'd be nice to have org.gnome.GEdit rather than

There's a kind of impedance mismatch between dbus and some more basic
ipc... with dbus you can have the bus launch things. So if you have a
.service file, you can just unconditionally do:

  app = new Proxy("org.gnome.GEdit");
  app.Launch(uris, props);

And gedit will be started if it isn't already, and reused otherwise,
with no race conditions.

Uh, with no race conditions affecting the number of gedit processes, I
think you mean.  There's focus and workspace race conditions, unless
D-Bus launches gedit appropriately (e.g. uses
libstartup-notification).  Is it possible to have D-Bus launch using
