set_close_on_exec for Netcgi sockets
Shouldn't the socket created by Unix.socket (Unix.domain_of_sockaddr saddr) Unix.SOCK_STREAM 0
on line 831 in netcgi_fcgi.ml
be set the close-on-exec flag? Indeed the process handling the FCGI connection may fork subprocesses in order not to block the main one (and these should not inherit the open socket).
