Thank you.

I don't disagree. The problem was, you were still talking about  
sockets. ;-)

Well if you really need data from the user then you'll need to find  
out how to do a non-blocking read from STDIN on Windows. This may or  
may not work in the popular Highline lib. I haven't yet found a need  
to resolve this long term problem myself, and as such I don't know how  
to yet. It's possible that Daniel Berger might know more, or that one  
of his Win32 projects can help you.

Again, I don't disagree.

It may well. It's important to note that the only problem is with  
STDIN when it's reading from the Console, it seems to work just fine  
reading from file (although I haven't done parallel file access under  
win32 that requires significant threading), and it works just fine  
with sockets.

It's a shame to loose a user to this, but it doesn't surprise me.
