Not yet, your other proposal of disabling SO_REUSEPORT makes sense if
we combine it with the proposal to change the score in my patch. If
we say that a socket which has SO_REUSEPORT scores higher, then the
connections which don't want to accept new connections anymore will
simply have to drop it an not be elected. I find this even cleaner
since the sole purpose of the loop is to find the best socket in case
of SO_REUSEPORT.
I'll give this a try and will submit such a proposal if that works
for me.
Cheers!
Willy
