Description

I found that when I bump the worker count up to 4 on my local box, the dedup nested in the optional appears to not be handled correctly.

gremlin> g = TinkerFactory.createModern().traversal()
==>graphtraversalsource[tinkergraph[vertices:6 edges:6], standard]
gremlin> g.withComputer(Computer.compute().workers(3)).V(1, 2).optional(bothE().dedup())
==>e[9][1-created->3]
==>e[7][1-knows->2]
==>e[8][1-knows->4]
==>v[2]
gremlin> g.withComputer(Computer.compute().workers(4)).V(1, 2).optional(bothE().dedup())
==>e[9][1-created->3]
==>e[7][1-knows->2]
