I'm going to be spinning up an Ubuntu box in the next few days that
will have a 5TB drive in it as well, so I'll be able to test to see if
the source OS (and/or version of SMB server) makes a difference.

I did an strace on '/bin/ls /cygdrive/t' on my host and saw almost the
exact same thing Warren did (slight re-ordering of events).  I tried
creating a new mount mount with 'noacl,notexec' as options since it
looked like maybe the has_acls() call was throwing the error in the
strace output, but my attempt did not work.  I'm going to play with
that some more this afternoon, though.
