gtk_progress_bar_set_fraction is a cpu pig, why??

[Dave Andruczyk <djandruczyk yahoo com>]

I have an app that uses (GTK+-2.4.1) gtk_progress_bars to display information
in a graphical way,  updating more than  a few each time new data comes in
(20times/sec) results in abnormally high processor usage for my app and X.

I've traced it with a profiler, and the gtk_progress_bar_set_fraction() is the
call that causes all the trouble.   How does one enable GTK to be compiled with
profiling enabled so I can find out why the hell this is so inefficent?

I have other gtk apps (gtk-1.2 actually) that use
gdk_draw_points/lines/rectangles that draw 50,000 points/lines per second with
only about 5% X11 usage and 2% app usage.  

updating a progressbar should NOT be such a pig in resource usage...
