Seems there's some repository damage on the server side. Works fine up
to here:

hg clone -r 1944 -U --debug http://hg.cython.org/cython cython2

But revlogs that are part of later revisions have gone missing:

http://hg.cython.org/cython/rev/1945
http://hg.cython.org/cython?bases=7975aadd82b76897c07336036305ed49b08549e8&cmd=changegroupsubset&heads=7975aadd82b76897c07336036305ed49b08549e8

Probably need to bring the folks on the server side into the loop here.
