I was wondering, though, how a local transaction becomes unset.  I think
we need to flesh out the interface a bit more.  It looks like a
connection that calls setLocalTransaction() can only participate in one
transaction.  I don't see any code that clears _transaction when it
commits.

I'm also not clear on what happens when a Connection calls
getTransaction() before setLocalTransaction().  It looks like the
Connection will get hooked up to two transactions.
