152 # WAIT argument is non-zero, smf_kill_contract will wait
153 # until the contract is empty before returning, or until
154 # TIMEOUT expires.

157 #
158 # smf_kill_contract 200 TERM

166 # via TIMEOUT) in 10ths of a second. This is because we want
167 # to sleep for short periods of time, and expr(1) is too dumb
168 # to do non-integer math.
