The `unwind-protect` part does not look correct since the rollback is
always performed, even after the body form completed successfully and a
commit was done. Either a commit or a rollback should be done, not both.
Perhaps `condition-case` would be the better option, but then the error
would need to be re-raised after doing the rollback...

A minor mistake is the result variable not using an uninterned symbol
(or alternatively, `prog1` could replace the use of the result variable).
