I'm interested in the current usage of cpu – precisely cpu% and wait% – for each thread in a specific application. Is it possible to get that information from somewhere?
I know that top can split information per real thread (ones with pid), but it doesn't show the system/user/wait cpu usage split for each of them. I would also like some way to log that info. Do you know any apps (or apis) that can do that?

I'd look into SystemTap. This tool will certainly give you what you want. There is this example of profiling threads; don't know if it has all you want, but you could modify it so that it does.
