Let me update my source tree, re-build, and check.

What port are you using?  i386? amd64? other?
Hmmm.  A -currrent from just a few minutes ago builds and runs correctly 
on amd64 (using QEMU).

Anyone seen this, or know what it's about?

On NetBSD/vax, with 8.99.22 from today.

Removing any file that has disk blocks allocated to it:

If a file is small enough to have all the data in the inode itself, rm survives fine.
