A proposed fix is in gerrit 2096 (which alters afs_lookup to accomodate
this). I'm fairly sure it fixes this behavior; I'm just not sure if it's
okay to do that on other platforms, or if we need to restrict it to
solaris. It's at least the right thing to do on solaris, as other
filesystems in the opensolaris code have an explicit check to do this
exact thing.
