Cool.
Looks like I was able to induce a getblk with bonnie, with an uptime of only
about an hour:

# uptime 
 4:56PM  up  1:07, 2 users, load averages: 0.33, 0.42, 0.29

# top |fgrep getblk
18481 root      -4    0  1252K   612K getblk 0   4:51 20.31% 20.31% bonnie

I'll let it hang out overnight and see if it's still hung. Me thinks it is as
bonnie has written it's business to disk and isn't doing anything right now:

# bonnie -s 8192
File './Bonnie.18481', size: 0
Writing with putc()...done
Rewriting...

# ls -ald Bonnie.18481 
-rwxr-xr-x  1 root  wheel  8.0G Feb  5 16:54 Bonnie.18481

So...we *should* have a dump tomorrow.
