Finally a useful response! Thanks Frank. :)

On Ubuntu 10.04, I tried running the callgraph tracing example here:

But all I could produce were syntax errors.

I couldn't find a way to get gstack on Ubuntu 10.04. It's not part of 
Ubuntu's gdb package apparently. Sounds promising, though. Any idea 
where I can get it?

I'll have to look into this one as well, though it does not appear to be 
packaged in Ubuntu at the moment. I'll see if I can get source and 
install manually.
