Subject: Re: Hello, and a question about finding a defined Class from C

Not long after sending this I ran a little experiment to validate the
symbol IDs were the same between script and C code. My code below was
correct, the problem was that I was passing -r AIO on the command line
(in my debugger settings). Hence my extension init was running before
I had run the require 'socket' statement.

If anyone is interested in a IOCP wrapper for ruby on win32 I would
like to get some feedback/testing on the implementation.

Thanks, -j
