This is probably due to gnome-session (mis-)behaviour:
My test client gets a "Die" message from the xsm server and within a few
tens of milliseconds receives an ICE io error (as the server has quit or
broken the connection). According to
https://www.x.org/releases/X11R7.7/doc/libSM/SMlib.html#Sending_a_Die_Message
the server should wait for clients to close the connection.
