Yes. Especially as a sufficiently large file will fill up the disk and
never recover without manual intervention. I've been meaning to look into
this for a while, but never got around to it.

However, this shouldn't necessarily mean that we limit the size of what we
can theoretically validate. It just means that we should handle large files
gracefully (i.e. in chunks) and allow local installations to place
arbitrary limits on how large files they will allow (with a configuration
parameter or somesuch).
