Repeated executions show varying results: sometimes it's OK, sometimes it isn't.
I don't think it's a race condition in your code (although proper
syncing on the map would be the "clean" way to go).
I think that salience doesn't work properly )(6.0.0, OP used 6.0.1.),
if a fact is matched unconditionally by a high salience rule and the
same fact is matched using constraints in rules with lesser priority.
(Wasn't this recognized before as a bug in 6.0.x?)
