The problem with "w" (and "top" and "ps") was a deadlock in the kernel
and was fixed recently (like in the last couple of days).  If you have
rev 1.75 (or 1.73.2.1 on the branch) of sys/kern/kern_sysctl.c (and some
other related files that were updated at the same time) this particular
problem should be fixed.
