"cloning subrepo gnulib" fails

[Daniel J Sebald]

Thanks for this info on the web page:

"
This will clone two repositories, one of which is git. If you have 
trouble with the git:// url (e.g. due to firewall restrictions), try 
adding the following to your ~/.hgrc to use an alternative http:// url:

[subpaths]
git://git.sv.gnu.org/gnulib = http://git.savannah.gnu.org/r/gnulib.git
"

Is this a problem with configuration on the local end?  Or is something 
to do with too stringent firewall rules on the server end?  If the 
latter, gnulib maintainers should be notified because at 
http://www.gnu.org/software/gnulib/ they are suggesting:

[gnulib]$ git clone git://git.savannah.gnu.org/gnulib.git
Cloning into gnulib...
fatal: read error: Connection reset by peer
