Putting "ps -ef" calls into the sendsigs script, it seems that a
dhclient3 process is the culprit.  Inside the
"for seq in 1 2 3 4 5 6 7 8 9 10" loop in the sendsigs script the
process table looks like this:

After the "killall5 -9 $OMITPIDS" call the dhclient3 process is still
not quite dead and listed like this:

root      1682     1  0 16:08 ?        00:00:00 [dhclient3]

Any clue why killall5 did not manage to kill it for good?
