It might be worth adding exist_ok to the filesystem interface. Python has this kwarg for os.makedirs (but not os.mkdir) to say not to error if the directory already exists (defaults to False).

Before adding more things to the interface, I would prefer that we continue to settle the discussion on a uniform file interface between dask, Arrow and others. Then we actually know to what we all want to converge to.

Maybe worth opening a JIRA about this in either case
One race condition was already fixed, but another one exists when writing by partition.
