Subject: Re: Unable to do non-blocking read on socket

Matz,

I tracked down one reason why we are seeing different behavior.  I was 
following the documentation which specifies that the Fcntl constants should 
be used on an fcntl call (which does seem reasonable).  In addition, the the 
socket source file in Ruby, O_NDELAY is also used.

You are using File::NONBLOCK.  And, indeed, File::NONBLOCK appears to work.  I 
am still testing so I will let you know if I run into anything else.
