The error checking in the TCP/IP layer is usually sufficient, but not
always. The checksum is short enough (32 bits, if I remember correctly)
that errors can creep in. I have had it happen at least once to me.
Unfortunately, the errors are more likely the more you download, and the
more traffic there is -- meaning that at release time, for example,
things are most likely to break, when people download huge ISO files.
