Starting with Python 3.8, the interpreter raises a ResourceWarning
exception during garbage collection if it finds an unclosed file
descriptor. Because of where this exception gets raised, it's
ignored (but a warning is emitted on stderr).
Use a typical context block in our loop to load data files, so that
this condition won't occur.
