Being a voice crying in the wilderness, I have a an alternate solution 
ready, but in need of testing. Instead of select() (via pth) it uses 
AIO  to wait for input from the network. I've been working on a stress 
client as Chuck describes, but got hit by a landslide and haven't been 
able to finish it yet.

Chuck: wanna help me test it?
