blackbox: add pid to output

exchange: allow fallbackheads to use lazy set behavior
The common ancestor set implementation was made lazy a couple years ago, but
this piece of code still required processing the entire repo by putting set()
around the lazy set. The code was introduced in

lazy ancestor set was added.
Dropping the set() shaves 3.5 seconds off of 'push -r' in repos with hundreds of
thousands of commits.

function there.
