This program makes the same mistake as gtk-perf: it sends the drawing
requests, but doesn't wait for the X server to actually perform them.
So you are essentially profiling Cairo and Xlib.  You aren't seeing
things like "the X server takes 50% of the CPU time while the benchmark
is running".

If you download the gtk+ sources, check out 
gtk+/perf/gtkwidgetprofiler.h.  It has the machinery needed to wait for
the server to actually process your requests.

Manu Cornet (on the CC line) is my student for the Summer of Code, and
he's writing a torture test for theme engines that uses
GtkWidgetProfiler appropriately.  This can be used both as a benchmark,
and also a way to ensure the robustness of theme engines.
