It's a bit hard for me to believe that this is a common occurance. Were you using aero cable routing? With traditional routing where the housings arch over the handlebars, it seems to me these loops of housing would provide more than adequate stress relief by deforming the curve of the arches long before a housing would rupture. Aero routing constrains the housing much more closely so I guess it could happen there. I must confess, this is the first time I've never heard of a brake cable housing failing it this way.
Something else that doesn't make sense here is that the mail order places, including Nashbar and Bike Tools Etc. sell exactly the same housings for use with brakes and derailleurs. One presumes they must be compressionless to work with indexed shifters, and in some cases they are explicit stated as such. In a society crawling with product liability lawyers it seems impossible a company as large as Nashbar would risk selling these as brake cables if there was any evidence that they are prone to failure.
