Win32: Prevent listening sockets from being inherited by

Win32: Prevent listening sockets from being inherited by
the Apache child process, CGI scripts, rotatelog process
etc.  If the Apache child process segfaults, any processes
that the child started are not reaped. Prior to this fix,
these processes inherited the listening sockets which sometimes
prevented the restarted Apache child process from accepting
connections (ie, the server would hang).

The Sleep(1000) is a bit of a hack but it is sufficient I believe. All
that is really necessary is for the parent to give up its quantum and
allow the child to run. I could not get WaitForInputIdle to work properly.
Will investigate alternative solutions later.
