	Um, what? They ought to expect them--they're documented and I
explained just now that they happen.

	This is correct. As I said, Bugzilla will not depend on
rollback for correctness. The only time rollback will happen is during
a fatal error.

	The situation you specify will never happen in Bugzilla code.
Nobody will ever rollback and then return to another function.
