Comment (by pramsey):

 Yeah, a fast shutdown is a SIGINT, so maybe I'm just totally wrong, and in
 fact you've just found a case that doesn't interrupt very fast in one
 place... There's definitely interrupts all through the union and buffer
 code, but there's also some places (overlay validation) that could maybe
 run a long time? So whether you got a "fast" interrupt or not would be
 somewhat random depending on where the process happened to be when you hit
 the ctrl-c.
