That's easy enough. Add a target like _GNOME_SETTINGS_VERSION of INTEGER[]
type to the _XSETTINGS_Sn owner of g-s-d. (What's required for this should
be documented.) Then request conversion of the selection to that target.
If conversion fails, g-s-d isn't running. If it succeeds, then you can
check the value to see if the settings daemon does what you need it to do.
You could use some stringy target like a name, but why compare strings
when you can use ints?

But alas, despite it being the standard method, everyone hates proper
selection handling, so you'll probably want to add a property to the
owner window instead. Adding one to the root window would be eat cycles
as every root listener will be processing a change. Using a pid won't
work remotely without more trouble than merit.

In any case, the expectations of g-s-d need to be documented.
