Summary:                    Busybox ASH cannot trap
Description: 
The following script hangs up with
 kill -HUP %1
from the current shellm but not
with
 kill -HUP <processid> from another shell.

Without the trap, it does react to signals
from another shell, but of course it does not run
the signal handler.

This is a bug, right? Is there any way to make
the script handle a signla sent from another shell>


#!/bin/sh

cleanup ()
{
    echo "cleaning"
}
trap cleanup HUP

echo "sleeping "
sleep 100000
echo "done"

I do not see it hanging, the background process seems to be successfully
killed:

# ./ash
/.1/usr/srcdevel/bbox/fix/busybox.t1 # ./ash testcase.sh &
sleeping, pid 8809
/.1/usr/srcdevel/bbox/fix/busybox.t1 # kill -HUP %1
[1] + Done                       ./ash testcase.sh
/.1/usr/srcdevel/bbox/fix/busybox.t1 #

Can you explain more precisely your testcase?
