This is a bit weird.  How can you even call this method if the ctor isn't also
tagged NET_TEST?

I guess the constructor is called by some other NET_TEST
function, and our unit tests only create this object using
that function?

Good point. The problem was that HttpNetworkSession::CloseAllConnections was
inlined, so the linker was not able to see FlushSocketPools even though it was
not really intended to be called directly by net_unittests. Note that msvc
doesn't inline methods of exported classes.

   void CloseIdleSockets();
 
   TransportClientSocketPool* transport_socket_pool() {
