------- Additional Comments From sf@sfritsch.de  2008-01-18 07:17 -------
Joe's description of the problem in comment #16 is accurate.

I think I closed the race completely, because if the signal occurs between the 
check for die_now and accept(), the signal handler will only set die_now and 
not call ap_close_listeners() (because active_connection == 0). In this case 
the ap_close_listeners() is done in the while loop just before 
ap_process_connection().

But fixing it in apr, so that apr_pollset_poll, etc. have a defined behaviour 
would probably be better.

Maybe
