Matt - Klaas's patch applies clean to branch-1. I'd like to push it in for hadoop-1.0.2, you
ok? Thanks.

> The typed bytes format supports byte sequences of the form {{<custom type code>
<length> <bytes>}}. When reading such a sequence via {{TypedBytesInput}}'s {{readRaw()}}
method, however, the returned sequence currently is {{0 <length> <bytes>}} (0
is the type code for a bytes array), which leads to bugs such as the one described [here|http://dumbo.assembla.com/spaces/dumbo/tickets/54].
