 This bug is in busybox 1.0.0-rc2. When using lash exec
builtin with redirection, the opened file fd keep increasing.
For example, please try the following command with lash.

ls -al /proc/<lash pid>/fd
exec /bin/sh 2>/dev/null
ls -al /proc/<lash pid>/fd

  The last 'ls' command output will look like this. The fd
number 4 shouldn't exist.

lrwx------    1 501      100         64 Aug 13 13:56 4 -> /dev/pts/5
l-wx------    1 501      100         64 Aug 13 13:56 2 -> /dev/null
lrwx------    1 501      100         64 Aug 13 13:56 1 -> /dev/pts/5
lrwx------    1 501      100         64 Aug 13 13:56 0 -> /dev/pts/5
dr-xr-xr-x    3 501      100          0 Aug 13 13:56 ..
dr-x------    2 501      100          0 Aug 13 13:56 .

  This one-line patch fix this problem by setting CLOEXEC flag for
squirrel fd. Please apply.
