(pdag f dag &opt n-workers)

Executes a dag by calling f on every node in the graph. Can set the number of workers for parallel execution. The graph is represented as a table mapping nodes to arrays of child nodes. Each node will only be evaluated after all children have been evaluated. Returns a table mapping each node to the result of `(f node)`.

(pmap f data)

Function form of `ev/gather`. If any of the sibling fibers error, all other siblings will be canceled. Returns the gathered results in an array.
