If a file is big enough to want to resume the download once, you
almost certainly want to be able to resume it a second time. I would
recommend not attempting to do the entire read and write as a single
operation - read chunks and write them to the disk. This will attempt
to read the entire response into a gigantic in-memory bytestring, and
only then start writing.
