Also: if I'm understanding correctly, we're tombstoning the beginning of the
row here? ISTM tombstoning the end of the row will be more in keeping with our
advice that "querying from the start of the row in comparator order is fastest."

It seems to me you would want this feature only when you have some sort of time
based column name scheme, and thus you only want to save the most recent n
samples. Thus tossing out the old ones.
