change

to figure
out a good way to print the load and process info, I'd favor at least
reserving a NOKERNINFO flag for the possibility of future use, along with
explicitly ignoring whether or not it was set for now. That way, code
that
wanted to control that feature would not have to be changed if it were
later
implemented (call it both more nearly portable and forwards compatible).
Printing the info shouldn't be too hard, but the question is if this is
a desirable, clean feature we'd like to have. The whole notion of the
kernel printing info to the user's terminal is, well, dirty. Though
there certainly is some precedent, like the dreaded "NFS server not
responding" messages.
Let's not print from the kernel.... utilities and shells that care
to do something useful w/ SIGINFO can; everything else should ignore it.
