IMO, the robustness choice outweighs this consideration. While a lot
of these scripts are for a single-purpose session, I'm finding that we
check them in somewhere and adapt them to future bugs. I'm sure
they'll break in all sorts of interesting ways; I'd rather not add one
that we *know* will end in breakage.
