 15 minutes after I submit the bug report, I have a fix -- another
 demonstration of why open-source/software built by people who want to,
 rather than *have* to, is such a wonderful thing. I go back a lot of
 years with Richard Stallman at MIT, and it still amazes me how right
 this is.
 
 Thank you for the patch. Building a kernel is next on my agenda, and I
 will install the fix when I do. You've also made me aware that this
 problem doesn't affect i386 systems, of which I have one (and two
 AMD64, all sharing the same backup/archive scheme and disks). So to
 the extent I can substitute that machine for doing ext2 work (I'm
 going to migrate as much of my backup scheme to UFS as I can), I will.
 
 Thanks again --
