questions about supervisor behavior

[Seven Du]

Hi all,

I have problems on get the supervisor working.

I want to start a supvisor with 3 children, and then dynamically add
children. Everything works fine except that when a child crashes, the
supervisor doesn't know and then cannot restart automatically. What
I'm doing wrong?

Code in the following link.
