Hi,

I cannot think of a way; on the other hand, I don't think disabling the 
core dump is necessary either. Simply filtering out '(core dumped) ' is 
not pretty but still suffices for me (we can put that into a filter 
function in common.filter and if other people see other messages for a 
core dump, they can expand that list).

If we really want to disable core dumps, we should change qemu-io not to 
use abort() on -c abort (raise(SIGKILL) seems like a good alternative to 
me); or, alternatively, introduce a new command 'kill' which then does 
raise(SIGKILL) so we don't have to break compatibility.
