Of more concern than bugs are errors during download.  Yes, TCP has a checksum,
which is a CRC that quite frankly sucks when we're talking the amount of data
that kernel.org moves. So there's a non-zero chance you'll get bad data
downloaded.  And you really want to do a more effective data check  (MD5 or SHA
sum, or a PGP signature) *before* you decompress, in case the corrupted data
causes a spew of gigabytes of trash and fills your filesystem.
