And if the LAN repository suffers a catastrophic failure (or a backhoe
takes out their WAN connection) before the commit really finishes, the
WAN repositories will be left waiting indefinitely, unable to process
updates or commit, while the local user may think everything is fine.
I don't know the details of what Eric hinted at for 1.5, but I hope that
it sticks with the model of a single master repository where commits
must succeed before a commit request returns.
