        but it seems to have completely broken intr-handling in bash 3.0.

No.  Something else is at fault.  I'm traveling and don't have access to
Solaris 2.8, but can't reproduce it right now on the systems to which I
do have access.

Does ^C work to interrupt a normal process?  For example, can you
interrupt a `sleep' job with ^C?

No.  On Tru64 when I try

        echo $$; sleep 99

in a bash 3.0 window, pressing ^C does nothing.  It also doesn't show up
in truss, so it's never getting to bash.  Pressing e.g. ^Z does.

On Solaris, the only difference is that at least ^C is echoed to my
screen, though it doesn't interrupt the sleep *and* it doesn't show up in
a truss of bash.

When running a system call tracer like `truss', does pressing ^C while
readline is active even generate a SIGINT?
