I'm sure this has been asked before, but I couldn't find anything on the subject. How do wounding weapons and regeneration interact? For example, could you kill a troll with a plain old +1 Wounding Longsword by bringing its constitution to 0?

Relevant passages from the SRD:
Regeneration Creatures with this extraordinary ability recover from wounds quickly and can even regrow or reattach severed body parts. Damage dealt to the creature is treated as nonlethal damage, and the creature automatically cures itself of nonlethal damage at a fixed rate.
Certain attack forms, typically fire and acid, deal damage to the creature normally; that sort of damage doesn’t convert to nonlethal damage and so doesn’t go away. The creature’s description includes the details.
Creatures with regeneration can regrow lost portions of their bodies and can reattach severed limbs or body parts. Severed parts die if they are not reattached.
Regeneration does not restore hit points lost from starvation, thirst, or suffocation.
Attack forms that don’t deal hit point damage ignore regeneration.
An attack that can cause instant death only threatens the creature with death if it is delivered by weapons that deal it lethal damage.
Wounding: A wounding weapon deals 1 point of Constitution damage from blood loss when it hits a creature. A critical hit does not multiply the Constitution damage. Creatures immune to critical hits (such as plants and constructs) are immune to the Constitution damage dealt by this weapon.
