	Wait + signals

We had some bugs here which are hard to test in testsuite.

Bug 1280 (http://busybox.net/bugs/view.php?id=1280):
was misbehaving in interactive ash. Correct behavior:

$ sleep 20 &
$ wait
^C
$ wait
^C
$ wait
^C
...

Bug 1984 (http://busybox.net/bugs/view.php?id=1984):
traps were not triggering:

trap_handler_usr () {
    echo trap usr
}
trap_handler_int () {
    echo trap int
}
trap trap_handler_usr USR1
trap trap_handler_int INT
sleep 3600 &
echo "Please do: kill -USR1 $$"
echo "or: kill -INT $$"
while true; do wait; echo wait interrupted; done
