zombie alert! about supervisord HOT 3 OPEN

For our application (mentioned by @haraldschilly above), we have solve this problem by using dumb-init as the parent of go-supervisord:

~$ pstree
dumb-init─┬─supervisord─┬─node─┬─4*[{V8 WorkerThread}]
          │             │      └─5*[{node}]
          │             ├─sh───node─┬─node─┬─bash───tmux
          │             │           │      ├─4*[{V8 WorkerThread}]
          │             │           │      └─2*[{node}]
          │             │           ├─4*[{V8 WorkerThread}]
          │             │           └─5*[{node}]
          │             ├─sh───sshd
          │             └─10*[{supervisord}]
          └─tmux─┬─bash
                 └─bash───pstree

It would be nice if go-supervisord also handled the pid 1 problem, like the Python supervisord does, but it's not critical for us.

@haraldschilly Can you give more detailed information on the zombie issue? such as a your test supervisord configuration file.

And then I will do some test to fix your issue.

I would say that launching tmux and bash that requires interractive session will cause them to instantly stop, and then will be collected by supervisord and restarted.
Can you check by multiple ps auxf that pids of bash and tmux changes everytime you runs it ?
