So you have wpa_supplicant started in daemon mode by init?
I don't know who invokes ifup wlan0 on my computer, and when; but I
understand now that having it configured with the method "manual" causes
all scripts in /etc/if-up.d to be executed, and one of them is
/etc/wpa_supplicant/ifupdown.sh, which launches wpa_supplicant in daemon
mode, like in your case, except it is not done by init.
I don't know what the wicd daemon is for. Does it manage Ethernet
interfaces as well?
