My initial thinking is that thread documents would just have the union
of the terms (tags and otherwise) of all messages in the thread. So
they'd be visible only when querying, and not need to be dumped and
restored.

Before I get too worried about the UI (i.e. how does one specify that a
query is meant to be applied threadwise), I want to have some idea about
the time and space costs of maintaining those extra documents in the
database.
