# The runs of docs/design/017's first stage, from the repository's root, in
# steps (each fits a session's background limit), the binaries kept in
# $WORK (default /tmp/pure-026) between them:
#   runs.sh build       pure-serve before 017 (0b5fa1d, in a scratch worktree) and after
#   runs.sh memory      what an app costs a host (memory.py)
#   runs.sh isolation   two apps as two processes or one host (isolation.py, five rounds of 15 s)
#   runs.sh pairs A B   a host of one app before and after, rounds A to B in turns as 025 ran them:
#                       TPC-C in RAM (W=1, 64 terminals) and the bank's queries
#   runs.sh counts      the bank queries' instructions before and after (025's count.py)
# Each timed step waits until the Pi has been quiet (the last minute's load below 1.5).
