Is '/some/file' a flat file, or a .db created from a flat-file?
And if the latter, was the derived db updated after changes to

Not an 'academic' question - I am testing two similar checks against
'one of each type', same contents, for whitelisting, and the result
returned seems to be more sensitive to I/O variables than choice
of lookup methodolgy.
