> After introducing the {{KillPolicy}} in MESOS-4909, some interactions with framework developers have led to the suggestion of a couple possible improvements to this interface. Namely,
> * Allowing the framework to specify a command to be run to initiate termination, rather than a signal to be sent, would allow some developers to avoid wrapping their application in a signal handler. This is useful because a signal handler wrapper modifies the application's process tree, which may make introspection and debugging more difficult in the case of well-known services with standard debugging procedures.
> * In the case of terminations which do begin with a signal, it would be useful to allow the framework to specify the signal to be sent, rather than assuming SIGTERM. PostgreSQL, for example, permits several shutdown types, each initiated with a [different signal|https://www.postgresql.org/docs/9.3/static/server-shutdown.html].
