I agree that supporting mergemaster is not important, but it did work
perfectly as recently as two days ago.  Seems to me that the error
message from 'rm' is important aside from mergemaster unless I'm the
only one seeing it  -- I just don't know how to demonstrate the error
any other way at the moment.

I ran a ktrace on mergemaster to try to figure out what's wrong.
I can see the first 'rm -rf' traversing the tree and removing
lots of stuff, then hitting the 'directory not empty' then
chflags being called, and that's where this begins:

Does this give any worthwhile information?

BTW I did recompile world/kernel before doing this.
