Simone Bordet ddca8bc327 Avoid StackOverflowErrors when submitting changes.
These were possible on a busy server, when many new connections are
created, and each triggers read interest: one connection submits the
read interest change, then runs the changes, finds that another
connections is created, runs it, which schedule a read interest
change, and so on.

Now the code is simpler, and while we always offer to the queue,
it may even be faster.
