I think that's correct - which makes it a pain to try to get any real indication
of where problems are - I think you need to build a static libc for profiling, 
and static X-windows libraries too - or you get a completely skewed picture of
what is taking most cycles.

I wish I knew why profiling of shared libraries doesn't work - I'm pretty sure
it used to work on my old SunOS systems.
