TCP will use a simple checksum that makes it pretty reliable against 
most accidental errors ... and if you are using encryption (ssh or ssl) 
then it will most likely also detect transmission errors.

Mercurial do not duplicate this functionality. If you want to be sure 
that no errors are introduced while downloading then you can create a 
bundle on the server side, calculate a md5sum, transmit the bundle, 
check the md5sum, and pull from the bundle.

verify will however not check everything - that would take too much time 
to be worth it.
