I guess that is correct, since I did prior to this as usual a "make -jX
buildworld buildkernel", with META MODE set and filemon loaded. 

Another host, also at r322769, bails out with the very
same error when doing an update of the source tree, as shown below and the
"make buildworld" fails the very same :-(
