I think it might actually be safe in this case: if the file changes out from under your lazy I/O, far worse things happen in the gdbm library layer than in the unsafe-IO Haskell layer.

Right, but if you do something like do keys <- getKeysLazy db [.. some computation A here that may or may not evaluate all the keys ..] addRow db newRow [.. some other computation B that uses the key list ..] does B see the new row or not?
