 I reproduced this before I knew of the PR this morning in a NetBSD
 4.99.70 Xen3 domU, too.  (Its kernel is configured only to add cgd(4),
 VND_COMPRESSION, FFS_EI, APPLE_UFS, and putter/puffs.)  Attached is a
 transcript of the ddb session at the console.  I did not get the same
 effect on a NetBSD 4.0_STABLE Xen3 dom0.
