Sandbox outputs "/tmp/box/?" on the shell

[veluca93]

As in the title, when a Worker started from the command line receives a job (in this case it was worker 1), the sandbox gives this output:

/tmp/box/1
/tmp/box/1
...
/tmp/box/1
/tmp/box/1

that i don't think is the intended behaviour. This seems to be caused by line 1298 in isolate.c.

I'll check with Martin if there's any reason to be printing this out. You're right that CMS doesn't need it at all.
I might introduce a --quiet flag to isolate to disable this.
