Define "network error" not as CSMA/CD error (like a lost packet, a mangled
packet), but as a high level error, like an aborted TCP connection. Those
are
quite rare (in a sane configuration). And I think it's much preferrable to
handle an unexpected problem via an exception rather than testing for an
error
after every write to the network. (Similar for writing to files)
