For dependencies, I can imagine taking a lock on the parent task rather than
a team lock when dealing with the dependency data structures, and outside of
the lock perhaps do a quick check if there are any dependencies using atomic
load. I can't imagine how one could get away without that though, and while
that can scale well if you have many tasks that spawn many other tasks, it
will still act as a team lock if say all tasks are spawned from the same
parent task.
