how does an embedded Yaws shut down?

More precisely, when a regular node shutdown takes place (init:stop/0) where an embeded Yaws was started in an app supervisor, what happens to the currently open page requests? Are they killed or do they run to completion? For the latter case, is there a time limit for completing a page result during shutdown?

I will try and write myself a small test, but in case someone knows the answer, that could save me a bit of time.
