I have the same problem so I'm very interested in a solution...
I have tried everything I can think of. I'm currently locking on the
outmost level, so that every stage and node blocks is inside the lock. I
previously had it inside a node block but got the impression that the lock
only worked on the same node. But setting it on the outmost level still
fails sometimes, even for jobs execited on the same node...
So I think this is a bug somehow...
