Exactly.

I think it might be stem:

i.e. it will not immediately notice that Tor has closed the socket. I
don't see why it should be any different when a stem-application is
connecting to the filter instead. I'm not sure why this is the case, but
my bet would be that it's related to how stem does async IO.
