For example, I want to
(a) SIGSTOP all keychain-related daemons
(b) modify /private/var/Keychains/keychain-2.db directly by using sqlite3 calls
© then kill all processes from (a) by sending either SIGTERM, SIGKILL, SIGINT etc etc.
What signal is best for killing daemons so they won’t flush their state back to keychain?
