# smf_kill_contract CONTRACT SIGNAL WAIT TIMEOUT
#
# To be called from stop methods of non-transient services.
# Sends SIGNAL to the service contract CONTRACT. If the

# until the contract is empty before returning, or until
# TIMEOUT expires.
#
# Example, send SIGTERM to contract 200:
#
# smf_kill_contract 200 TERM
#
# Since killing a contract with pkill(1) is not atomic,
# smf_kill_contract will continue to send SIGNAL to CONTRACT
# every second until the contract is empty. This will catch
# races between fork(2) and pkill(1).
#
# Note that time in this routine is tracked (after being input
# via TIMEOUT) in 10ths of a second. This is because we want
# to sleep for short periods of time, and expr(1) is too dumb
# to do non-integer math.

# Returns 0 on success.
