Thanks for the quick explanation! I see where Server/start method
defines "handleSocket" as well, to get the show on the road.
And in your server sub-class, you re-define "handleSocket".

Did I say all that correctly? I must admit that I'm *very* new to
OOP! I've stayed away until I stumbled on Smalltalk, and then Self.
I preferred the latter, but had issues getting it to work properly
on the OS X box I was using at the time. Gave up on it. I'm hoping
that Io will be an eye opener for me! :)
