>Description:

The test case in /usr/tests/lib/libc/gen/t_closefrom fails when run when
invoked from a user with /bin/sh or /bin/ksh as shell, but works when invoked
from a (t)csch user.

>How-To-Repeat:

        cd /tmp
        /usr/tests/lib/libc/gen/t_closefrom closefrom_basic

Ktrace shows that fcntl(F_MAXFD) returns 3 in the csh case, but 9 in the
(k)sh one.

>Fix:
n/a
