Restarting zone1 over telnet can lead to zone1 locking up #16

Reported against: https://github.com/hex-five/multizone-sdk/commit/7edf433546d940b895c8d3aca0750fc86402c853

I experience a semi-random behavior when trying to restart zone1 over telnet. Zone2 remains functional as I can ping it still. LD0 and LD1 stop doing anything and stats show times < 10ms which indicates no tasks running in zone1.

Here are steps how to reproduce:

➜  ~ telnet 192.168.1.2
Trying 192.168.1.2...
Connected to 192.168.1.2.
Escape character is '^]'.
