So it never returns from the recvfrom call?

Is this actually the only time you see emacs hanging there?

I would guess that if it can hang in that case, you can device other
cases (combining more processes) that would make it hang there in case
any process changes state...

In what way is the network server process closed?

I agree that using delete-process should not call read_process_output
for the deleted process.  I just installed a change to avoid that.
