I've never heard of this before (although I might've read about it agesssss ago in teh manual (and probablyl dismissed it thinking that it was part of the alarm option), but I can say that I've definately noticed that sometimes when I lock the car I heard a nice little thud (deadlocks), but other times it's a lot quieter - I sometimes hit lock twice (with a few seconds in between) just to be sure.
Re. kids in the car - can't they just hit the unlock button on the drivers door if they need to get out? It might be worth testing and informing them (depending on their age, etc).
