^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
I would prefer to see this behavior instead of the proposed behavior:
"When any child process exits, the parent will terminate the
other worker processes and exit.
as it seems more robust. It also might provide a reasonable path
to eliminate the rebind limitation:
"On platforms with no IP_PKTINFO support ... disable reconfiguration
when worker processes are in use."
