Commands where launched twice

We were waiting to get 2 in tmp file, so all commands where launched once and
then once again.

After first time, tmp file was:
{
  "rc": [
    ("rc-file-name",
     ([
      { "commands": ("cmd1", 1) },
      ...
      { "commands": ("cmdN", 1) }
     ]))
  ],
    "daemon": 0
}

(we now stop here)
---------------------------------------

After the second bunch of launch
{
  "rc": [
    ("rc-file-name",
     ([
      { "commands": ("cmd1", 2) },
      ...
      { "commands": ("cmdN", 2) }
     ]))
  ],
    "daemon": 0
}
