Sure, [zero is] a reasonable default delay time to display

Or, you could make it something like 5 seconds or whatever.
The point of the delay time is to reduce the CPU impact
of a service that continuously crashes and gets restarted.
This makes the most sense for SC_ACTION_RESTART.
For SC_ACTION_RUN_COMMAND the admin could have the command
itself introduce its own delay.
