Yeah, that is a problem.  I've been bitten by that bug too. I had a tire 
essentially ruined but luckily I noticed it before I had a blowout during 
a ride.  Now I make a habit of checking them every ride.

No need to for just that reason.  You can use the Shimano V-brakes with 
the parallel-push mechanism (on LX and higher models, IIRC).  As the pads 
wear the angle between the brake shoe and the rim remains constant, so 
there's no danger of the pad eventually reaching the tire sidewall.
