On Windows, darcs repair isn't always sufficient, since there's no atomic
file rename over an existing file, so there's always a small window between
when we remove the old inventory and when we rename the new.  But that
*should* be a very small window indeed, and usually repair should restore
consistency.  I have some ideas that should massively reduce the sensitive
time during which we wish to block signals (and interrupts), but that'll
come after the conflicts stuff is coded up, unless someone beats me to it
(and there was an interested developer on the project).
