After a quick look at gnome-settings-xrdb.c
It seems that the style_set_cb callback, which ultimately spawn the xrdb 
command, is called multiple times.
This happens because the style_set_cb callback is connected to the 
GtkWidget signal "style-set"
which receive multiple "style-set" signals (8 or 9) initially for the 
same theme.

One solution to avoid these multiple calls would be to monitor the gtk 
theme Xsettings property
as gtk does (via "notify::gtk-theme-name") or the 
/desktop/gnome/interface/gtk_theme gconf key directly
instead of relying on the "style-set" signal.
This way only complete theme change would trigger a xrdb change.

   Cheers,
