ruby 1.9 with nonblocking connection

[Subbsd]

Hello,

I'm trying to use selenium in ruby (ruby-1.9.2.290_2,1) script, but
get an error like this:


/usr/local/lib/ruby/gems/1.9/gems/selenium-webdriver-2.8.0/lib/selenium/webdriver/common/socket_poller.rb:63:in

at the 63 I see the following line on socket_poller.rb:


62          begin
63            sock.connect_nonblock sockaddr
64          rescue Errno::EINPROGRESS

any idea of what could be the reason for such behavior? Thanks.
