For nmany applications, a pretty good good (intrusive) way to figure out
when the app is up on the screen and painted is to put
a g_idle_add() into an expose handler; applications will typically 
handle all exposes before going idle again.

I believe this is 'strace -tt' measurement? My experience is that that
can be quite distorting because it greatly magnifies the per-syscall 
overhead.
