Modified: src/main http_main.c
Log:
When the network layer has been shut down, there
is not much use in just exiting: the parent
would simply re-create us (and we'd fail again).
Use the CHILDFATAL code to tear the server down.
This fixed a nasty fork-loop bug which appeared
in these network-shutdown situations (children would
exit and be recreated immediately).
