Gateway hosts forward broadcast packets =>problems with loops

[sanjay Radia]

I saw a couple of fixes to allow gateway hosts to forward broadcast packets.
Won't this cause probles if there are loops in the network topology?
Wouldn't it be better for applications such as rwho to send a broadcast 
packet for every net (ie fill in the net part of an address but set the host
part to zero). I think 4.2 will forward such packets.
