---------------------------------------------
I'm all for putting this in contrib. Let's hold the bar relatively low and
wait until it proves itself to graduate it elsewhere.
We could record the start of the first duplicate of a block's leading key
earlier in the file. This might allow a relatively efficient skip to the start
of a block of duplicate keys that cross a block boundary. If you just store
the distance in uncompressed bytes, you can probably sort the rest out.

> SequenceFile's block compression format is too complex and requires 4 codecs
