git clone against firewall

[Sebastian Pipping <webmaster@hartwork.org>]

hello!


with a firewall blocking outgoing connections to port 9418 a

  git clone git://...

of git 1.6.6 seems to never return, i.e. loop forever.  in my rather
automated environment (gentoo's tool layman calling git) this behavior
is rather troublesome - i need some kind of abort-and-error instead:
what i'm trying to do is loop over a number of clone URL alternatives of
the same repository like ..

  git://git.overlays.gentoo.org/dev/dberkholz.git
  http://git.overlays.gentoo.org/gitroot/dev/dberkholz.git
  git+ssh://git@git.overlays.gentoo.org/dev/dberkholz.git

.. and stop at the first clone that returns without error.

are there means to make git fail in such a case or to apply a timout?
if not please consider adding a related commandline option to git-clone.

thank you.
