# The runs of docs/design/017's 2b, from the repository's root, in steps
# (a step at a time: a background job may be stopped after half an hour).
# runs.sh build the builds, each in /tmp/pure-028/NAME with its
# pure-crypto.so: before (a thread a link, 3791ab8),
# threads-push (before with threads-push.patch: the
# owner pushes a turn's sends at once), loop (one
# sending loop, 32f96b3), push (the loop with push,
# 6d3c3c2)
# runs.sh links five rounds of 1,000 bursts by one link, four links and
# one wire, the builds in turns, once the last minute's
# load is below 1.5
