#15 1-wire network short circuit silently kills dz

No

Short circuit on 1-Wire network, as well as any other
irrecoverable problem (such as 'Error communicating
with adapter'), renders DZ inoperable with no clear end
user notification.

The architecture must be revisited in such a way that
as soon as a serious problem arises, the end user is
notified.

Exception trace, for the record:

    Fixed. The fix is ugly, but it doesn't make sense to make it
    nicer because there's a chance that all the data and control
    flow will be revisited soon.

    CVS access is barely functional at this moment, it may take
    a few hours for the fix to be submitted.
