Right.

I was copying from a fat32 partition to an ext2fs partition on the same
USB drive, so this fits.
Meanwhile, I finally had a chance to stress test John's locking patch.
It successfully passed a make -j2 buildworld/buildkernel with src and
obj on the same partition, and a ports build of libreoffice (and its
several dozen deps) with ports and WRKDIRPREFIX on the same partition,
part of which overlapped with the world build.
