moses in server mode

Hi all,

I'm using a system with current CentOS 7, Boost 1.60.0 and moses from
git master (SHA: 42b8b89d54a5c670f02a16426a92cc1d0fb97754).

While playing with basic hierarchical models I found the following
(probably buggy) behaviour:

1.) INITIALIZE ...

% wget "http://www.statmt.org/moses/download/sample-models.tgz" && tar
xfz sample-models.tgz && cd sample-models


2.) TRANSLATE WITHOUT SERVER ... (ok)
