Folks, for all of you who have been seeing those hangs when
you run ps/top/w while the system is under load, this fixes
the problem. I have pulled the change up to the netbsd-1-5
branch, as well.

Subject: CVS commit: syssrc
Module Name: syssrc
Committed By: thorpej

Modified Files:
syssrc/sys/kern: kern_sysctl.c
Log Message:
In fill_kproc2(), testing p->p_stats != NULL doesn't do much good,
instead test for (p->p_flag & I_INMEM), and don't access the U-area
(via p->p_stats) if that bit is clear. Fixes the hangs people have
seen when the system is paging and the user runs top/ps/w.
