No, it's not a race.  When this is occurring, processes sit in
"exiting" for several minutes like that, doing (apparently) nothing.

What's weird is that I was able to unmount the nullfs mount, but not
the NFS mount, even though the process would have had to access the
NFS mount through the nullfs mount.

Thanks!
