interestingly, this doesn't seem to happen (or happens less often)
when I use my WiFi at home...

The difference between mine and other networks (mainly in school) is
that at home is only one access point (one SSID and one AP).
In school I have few SSID, though most of the times only one is
available. Though that SSID has multiple access points, I also
generally open laptop at different location than when I closed it.
Beacon frames are being sent less frequently (at least I belive so) at
school's network.

Though, that sudo iwlist scan in that situation often returns with no
results without even thinking (scanning) is not correct. I often run
it several times before I call sudo killall wpa_supplicant.
