It is, and I don't think there's any possibility of turning that off.
It's too tightly integrated with the cross-backend interlocking.
If you don't want transactions, and you don't want multiple backends,
maybe mySQL is what you need ;-)

BTW, if you're not too concerned about parallelism, one way to squeeze
a little more speed is to use explicit transactions *more*, not less.
The more stuff you get done between BEGIN and COMMIT, the less the
transaction overhead per useful operation...
