Home-grown, but removing it completely (which causes the default look) makes
no significant difference.

No, massif is not available for ARM; oprofile requires Linux 2.6 for ARM
support.

Thinking about this a different way, is there any benchmark program for GTK? 
Then at least I could run that against different versions and get a feel for
what to expect (we also have a build with GTK 2.10).
