This is very helpful.  Following this suggestion, I put at
the end of the ifup-wireless:

# Bring up wpa_supplicant if needed.


if ! ps -ef | grep -v grep | grep -q wpa_supplicant; then
   if test -n "$ESSID"; then
      for ii in thisSecureWiFi thatSecureWiFi theOtherSecureWifi; do
         if test $ii = $ESSID; then

if test $suppl = yes; then
   wpa_supplicant  -w -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf 

Now I do not have the wireless coming up automatically, but
if i click Activate in Network Device Control, the connection
is made with reasonable reliability.

Now I would like to bring down wpa_supplicant when I click
Deactivate, bit I do not see a "ifdown-wireless" script.

What script is called in this case?
