Subject: [ruby-talk:11552] Re: TCPSocket Problem?

Thanks for the info Matz do you think I should try 1.7.0 or is it not stable enough
yet?

I don't know what your problem is Joathan but if it is related to the two initial
sockets being opened I don't have a problem with this as one or two file descriptors
are not going to hit my limit!

My concern is a file descriptor being opened every time I call TCPSocket::recvfrom.
