You can specify delays in config.js to get process switch more smoothly. (Use can use 500 ms. Default 0)

I have made three actions not listed in task in app2.

1. I was need to consider a case when parent process has exited before I kill it. I record in log this action.
2. I was should not to spawn new child if I have spawned another one before. Otherwise we can get uncontrolled growth of processes.
3. If new process starts after parent has exited - ID is expired. We need to get new one for new process. Otherwise "identifier does not exist" will forbid process exit.

I attached example logs with comments - app1-fast.log and app2-fast.log These logs are result of apps with delay == 0.
