 Good point, but I do think a nosymfollow is a good default.  There's really no 
 reason to allow /tmp symlink race conditions to happen.  SInce it's a memory 
 fs, disabling atime doesn't really make a big difference.
 
 Anyways just a suggestion, I'll be definitely setting nosymfollow on my 
 machine here.
