I have a program that works under Windows XP and Ruby 1.8.5. I just  
switched to 1.8.6 and a new bug appeared.

In net/imap.rb, there is a statement “@sock = TCPSocket.open(host,  
port)”.  
If host is a remote URL (e.g., [www.anywhere.com](http://www.anywhere.com)), it works. If host is  
“localhost”, or “127.0.0.1”, or my local Host Name, or my local IP  
Address,  
it fails with “Bad file descriptor - connect(2) (Errno::EBADF)”.

Since most of my test sites are on my local computer, this makes testing  
difficult, if not impossible.

Help?
