Addressed in <629C022B-BF10-4461-9D52-8F305D2051DC@pobox.com>.  Please  
respond there.

Marc and I are disagreeing with what I wrote in the message included  
in <E5761512-9F7F-45ED-9C45-A8D9FFFC8C9C@pobox.com>.  No amount of he- 
said/no-he-said will resolve it at this point, so I refer the reader  
back to the actual exchange.

Everyone: Your suggestions to improve my communication are greatly  
appreciated.  Please comment off-list, if you can.

I explicitly stated otherwise in the message included in <E5761512-9F7F-45ED-9C45-A8D9FFFC8C9C@pobox.com

AnyEvent::Impl::POE's public interface".

Considering our previous discussions on the matter, I feel that your  
conclusion is premature.

Also, you seem to be saying that one solution can simultaneously  
perform equally as well as another and worse than it.  Which quantum  
computers have you ported AnyEvent to lately? :)
