Subject: Help begin/rescue/ensure

I have this simple code.

require 'rubygems'
require 'net/ssh'

begin
  session = Net::SSH.start('aaaa-lnx', :password=>'xyz',
              :username=>'root',:timeout=>5)
rescue
  puts 'cannot connect '
ensure
  puts 'reach ensure point'
end
puts 'at last'

--------------------------------------

If I put in non existing host name (aaaa-lnx), then the statement
"puts 'at last'" won't print out.
The ensure blocks work fine.  Somehow, the "rescue" block can't catch
the error.   This is my output.

reach ensure point
/Applications/Locomotive2/Bundles/standardRailsJan2007.locobundle/i386/lib/ruby/1.8/timeout.rb:54:in
`open': execution expired (Timeout::Error)
        from /Applications/Locomotive2/Bundles/standardRailsJan2007.locobundle/i386/lib/ruby/gems/1.8/gems/net-ssh-1.0.10/lib/net/ssh/transport/session.rb:88:in
`initialize'

If I put in a good hostname with wrong password, the "rescue" block
will catch the error just fine.  Here is the output:

cannot connect
reach ensure point
at last


What did I do wrong ?

Thanks,
