hg clone is unbelievably slow

Half an hour or more here.  AFAIK the problem is due to the
inefficiency of Mercurial itself and the hg protocol.

Aleksey Shipilev has done an experiment whereby trees are regularly
cloned and compressed tarballs created; these can be downloaded in a
couple of minutes.  But really we don't want to depend on the largesse
of one developer: if we could download the OpenJDK trees directly by
means of wget (or something similar) we would reduce the load on the
servers and reduce the time taken to download as well.
