I have no problem backgrounding a process, getting a message saying that
it has stopped waiting for terminal input and foregrounding it to talk
to it.  On the Suns, gcore will get you a core dump of a running process
allowing you to interogate it using your favourite debugger. So your problem
should go away now that bsd and svid are merging.
