I didn't plan to.  Perhaps we should set fs_maxfilesize to 2G-1.  This
should be safer than doing nothing or attempting to trap all the overflows.

I thought that large files worked in -current.  A long time ago, I put a
1 TB file system on /dev/vn0.  The metadata must have gone beyond 2G
logical in the underlying file.
