Eric,

first of all this is not a bug report, but just trying to understand  
what might be the problem.
If I knew what the problem is I was not asking if there is any known  
issue, a fix, or something.
I've read the archives before posting and there are some guys with  
similar problems but no answers.

I know that the select() function on windows is quite different and  
not very handy.
One thing is weird for sure, similar code works just fine on Unix but  
is not very performante on Windows.

I want to know if someone have found some way to deal with this  
strange issue.


Thanks
