That's not the important part. The issue here is that I am noticing that whenever certain operations on devices, such as ppp waiting on a connection, or a process waiting for a disk operation to complete, it cannot be terminated or killed if you have given up on it. Neither a ^C/^\, nor kill -TERM/-KILL from another command line. Unfortunately, other than the ppp example, I don't remember off hand a specific example involving waiting for a disk operation, but that has happened to me to. (A ps reveals a D flag on STAT). I guess I am wondering if such an annoying trait is someone predestined due to hardware constraints, or if it is more of a software design issue. What if an "uninteruptable operation" has failed, and you need to kill it? And, if it is a software design issue issue, how come it hasn't been "fixed"? Is such an change actually much harder than it appears?
