In the GNOME environment, after exiting the application, the gsettings monitor org.gnome.desktop.interface process becomes a zombie process.

[c-xk]

I don't know if this issue exists in other environments, but it can be consistently reproduced in the GNOME environment.

Steps to Reproduce:

1. Run GuiDemo or OsThemeDetectorDemo
2. Observe the spawned processes

3. Close the GUI window or terminate the demo
4. Check whether the processes observed in step 2 have terminated

Expected Result: All processes observed in step 2 should terminate.

Observed Result: The gsettings process does not terminate. Each time the demo is run, a new gsettings process is created.
