I haven't checked, but the rollout logs (which I put in to debug the
changes to rollouts I was making) were completely non-thread
safe. There was a single file handle to which all moves were being
output. I tried using it once a few months ago and the results were
useless.
If the file handle, file names etc. have been moved into a
thread-local data structure then it will work again (modulo sufficient testing)
