Not really, there are a surprising number of apps that consider abort() to be 
a normal way of exiting when there's a minor problem. I've never seen any app 
catch SIGSEGV and then raise(sigabort).

No, its because you get a lot of programs ending with abort - hald-addon-acpi 
and dhcdbd to name a couple.

It was frequent enough I didn't want that noise in the logs at this point. If 
those applications get cleaned up, I think we could allow abort() to go 
through.
