I've attached a file with many of the values you have asked for. We
looked at some of the threads referenced by td->td_proc->p_threads, but we
weren't sure we were walking the list correctly. Do you have any tips for
walking those thread lists?

The programs named by p->p_comm is linked against the pthreads library.

We can upload the source, kernel etc somewhere, but uncompressed that is
about 5G of data. What is the best way to get that to you?
