Your program doesn't have any threads, so it will execute in lock-step. 
That is, when you enter pass, you will sleep for 60 seconds there, 
before returning.

Try adding some puts statements to see what's going on, e.g.

> class Test
> 
> def initialize

puts "start initialize"

>   @junk = Array.new
>   @opensocket = TCPSocket.new('localhost', 8080)

puts "socket open"

>   read

puts "read has returned, done initialize"

> end
> 
> def read

puts "start read"

>   while @lines = @opensocket.gets
>     FasterCSV.parse(@lines) do |@row|

puts "Read line #{@row.inspect}, going to pass"

>         pass

puts "pass has returned"

>     end
>   end

puts "done read"

> end
> 
> def pass

puts "starting pass"

>   @junk << @row

puts "sleeping for 60..."

>   sleep(60)
>   p @junk
> end
> end
> 
> enable = Test.new

You could alternatively try to use a debugger to single-step the 
program, but generally I find the hassle of learning to drive the 
debugger to be higher than putting the debug statements in.
