No, adbapi does use threads. That's the only way to take advantage of
the existing blocking database client libraries.

It would be nice to do it without threads, but nobody's written decent
asynchronous implementations of the database protocols. (There's one
in the postgres client library, but I haven't seen anything good come
of it).
