What I've done on our system is to comment out the sleep:

line 310 of daemon.c
(void) close(DaemonSocket);
DaemonSocket = -1;
refusingconnections = TRUE;
/* sleep(5); */
continue;

It seems to work ok, and does not reject connections for 5 seconds each time
accept returns -1. It might not be a proper fix but it works.

Regards,
Jim
