- Removed per_iteration_data struct. - This struct was being used to pass in a thread id to each pthread but that thread_id may have been overwritten before creating the next thread. - The thread id and message size was moved to the per_thread_data struct which is then passed to pthread create in an effort to avoid the race described above.

I find this way of passing data to the thread function much more readable than what was there before.
This struct was being used to pass in a thread id
to each pthread but that thread_id may have been
overwritten before creating the next thread.
The thread id and message size was moved to the
per_thread_data struct which is then passed to
pthread create in an effort to avoid the race described above.
I'm not sure if theee is a race here before this PR but it looked like the thread id field of the other key could get stomped on between calls to pthread create.
