Status code == 0 when jack not started

[SrMouraSilva]

When the mod-host runs without a server running jack, error messages appear, the mod-host is terminated but the status code of the returned mod-host is zero.

mod-host$ sh -c './mod-host'; echo $?
Forking... child PID: 11341
0
mod-host$ Cannot connect to server socket err = No such file or directory
Cannot connect to server request channel
jack server is not running or cannot be started
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for 4294967295, skipping unlock
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for 4294967295, skipping unlock

In my conception, a code status should be returned equivalent to an error.

It is terminated to 0 due to the fork performed.
