A cycle builder does the following;

while true:
   if new_upstream_revision:
      update_to_new_revision()
      i = 0
   run_all_tests --seed=i
   save_data(i, revision)
   i++

Basically, it sits at the current HEAD and just runs the build over and over collecting the results.

Any time HEAD changes, it updates to HEAD and then starts from the beginning again.

@acomodi - This relates to trying to get more statistical confidence in the output.

It also assumes the tree HEAD is moving slower than it takes to run the tests.

Due to people (hopefully) not working on the weekends, I expect that commits on Friday will get a lot more data.
