What would happen if someone swallowed super glue?

If already set: nothing serious; you'll likely poop it out like chewing gum.

If fresh: Nothing good, but very luck dependant.  It will irritate mucous membranes as it polymerised rapidly in the moist environment.  The worst case would be lodgement in the trachea, which could block up solid, leading to suffocation. 
The best case would be sliding down a well lubricated esophagus without much interaction, then landing in a stomach partially filled with food to bind with.  This outcome would lead to large, difficult to pass bowel movements, perhaps serving as a reminder to not swallow superglue.
The actual term, superglue, can refer to any mixture of a family of rapidly polymerizing monomers called cyanoacrylates.  These vary in toxicity, however the most commonly used have very low toxicity, and mostly won't be able to reach the bloodstream via the scenario you described, as they cannot cross membranes in polymer form and there isn't a biological mechanism for breaking Carbon-Carbon single covalent bonds in the digestive tract.  Some cyanoacrylates are relatively volatile and can be absorbed in the respiratory system, where toxicity concerns become more relevant.
