#48 leafs delink from slaves when main goes down

[patrick]

When I kill my main the leafs disconnect from their slaves.
It somehow thinks that the slave went down instead of the main.

debug output of a leaf:

// first link
[*] Acting as LEAF
[+] Config loaded
>>> hub = hub
[*] Connecting to HUB: localhost port 4848
..
[D] hub handle: slave

// then when it sees main quitting:

[C] read[]: 62 hub * 38 EOF from client
kill:
red kill:
>>> hub = hub
[*] Connecting to HUB: localhost port 4848
..
[D] hub handle: slave

occurs at least on 0.2.14
