Done, and now

 [x86_64 20140514]> id Administrators
 id: Administrators: no such user
 [x86_64 20140514]> +Administrators
 uid=544(+Administrators) gid=544(+Administrators) groups=11(+Authenticated Users),544(+Administrators)

with no delay in either case.  So _that's_ sorted.

Overall, I now get the following clean pattern of id behaviour
wrt prefix '+':

                w/o      w
                 +       +
SYSTEM          no      yes
LocalService    no      yes
NetworkService  no      yes
Administrators  no      yes
TrustedInstaller no      yes
Administrator   yes     no
cyg_server      yes     no
Guest           yes     no
ht              yes     no
postgres        yes     no
sshd            yes     no

[you can reproduce this using
  > cut -d ':' -f 1 /etc/passwd | while read u; do echo -n "$u  "; if id $u >/dev/null 2>/dev/null; then echo -n "yes	"; else echo -n "no	"; fi;if id '+'$u >/dev/null 2>/dev/null; then echo "yes"; else echo "no"; fi done
