[issue1850] Can't push changes to a repository that contains sub-repositories when the host the sub-repo was cloned from is offline

[Monroe Williams]

New submission from Monroe Williams <monroe at criticalpath.com>:

Setup: 
- create a repository on host A which references a sub-repository on host B.  
- clone the repository onto host C
- take host B offline
- commit local changes to the repository on host C (not in the sub-repo, but in the main repo)
- do an 'hg push' in the repository on host C

The push will fail trying to contact host B.

Traceback looks like this:

$ hg push --traceback
pushing to ssh://hostA.something.com/mumble/
pushing subrepo path/to/hostB/subrepo
Traceback (most recent call last):
