Hi,
Just a quick question:
While dialing out to my ISP one night, I noticed that the
company's phones were done. 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?
Thanks,
drifter
