The simplest artifact is observed by watching the output of
adb shell dumpsys meminfo -d phone | grep 'Proxy Binders'
while turning airplane mode on and off (slowly, to allow the
cell network to connect and disconnect).
This will display the number of binder proxies. Before this, the binder
proxy count increases by 2 with each connection and never goes down (there
is some noise, as proxy objects are sometimes created for other reasons,
and get GC'd eventually). After this, the binder proxy count is always
eventually stable.
