 Hypothesis: select() under sunos 4.x wakes up all waiting children when an
 event happens.  All the children then race down to the accept() and block
 in there.  That'll spike momentarily.  Most OSs have this behaviour
 actually. 
 
 See <http://www.apache.org/bugdb.cgi/full/467> and give the suggestions
 there a try.  That should achieve the same thing as your patch without
 requiring you to hack up the code (and also supporting multiple Listen
 statements, which yours doesn't). 
 
 It's looking more and more plausible for us to use serialized accepts on
 all architectures. 
 
 Dean
