Files.walkFileTree

[Benedict Elliott Smith]

For very large directories it is useful to be able to perform a walk with
multiple threads - i abandoned this API in a project recently for that very
reason. Obviously a File.walkFileTreeConcurrently() (or similar) method
would have to error if any method result was SKIP_SIBLINGS, and accept that
TERMINATE would not effect an immediate stop.

Not sure if you're desperately keen to add such functionality, but it might
be worth considering while you're looking at it.
