To elaborate a little bit on my last comment (which I submitted very quickly when my bus was arriving), the way to make dependent tasks with dask.delayed is to add dummy function arguments, e.g., ```python def finalize_store(store, write): del write # unused store.sync() store.close()

write = dask.array.store(..., compute=False) write_and_close = dask.delayed(finalize_store)(store, write) write_and_close.compute() # writes and syncs ```

Potentially some of this logic could get moved into ArrayWriter.sync()
