[issue1777] Corrupted repo using 9p network filesystem

[Micah Stetson]

New submission from Micah Stetson <micah at stetsonnet.org>:

The second commit to a repo mounted over 9p on Linux seems to corrupt the
repo.  I'm using Ubuntu jaunty.  I've tried this with hg 1.1.2 (the one that
comes with Ubuntu) and a freshly installed 1.3.1.  Below is a log ('%' is my
shell prompt), and I've attached a tar of the repo after running these commands.

% hg --version
