I think they are now a violation of the NEC. And they were delisted by UL years ago. They pose a hazard as they will not react fast enough to prevent a fatal shock. (and the only one's I've ever seen were outlawed as the breaker itself was a fire hazard.)
While I do not have a copy of NFPA 70-2011 (the latest latest, released a few months ago), my reading of NFPA 70-2008 still allows GFCI breakers (NFPA 70 is the official name for NEC). Personally, I prefer to specify and use GFCI outlets (and I tend to not daisy chain) so that the the fault is next to the use (and no collateral outages occur). Of course, specific breakers may not meet the newest requirements.
