Yes.  I removed it (all of /usr), and all's well.

I must have done that deliberately, in a fit of security
consciousness, but I'd completely forgotten.  Thanks for helping me
track that down.

I had sprinkled nosuid and nodev over lots of things; I've now removed
them.  I started with /usr, but then realized /var probably needs it
off too (since some stuff runs chroot there, or at least runs
there--hylafax, I think).  And maybe I'll build something in
/usr/local that needs it.  So I just took it off everywhere.
