Yes, this is dangerous because it shares the "dirstate", which keeps
track of what revision is checked out, and what files are
added/removed/etc.

The store is actually -designed- to be shared, but we haven't yet
decided whether the issues with rollback/strip/mq are worth worrying
about so it's not a feature we really advertise.
