Subject: Re: Generic ? regarding Threads

I did some very minor experimentation back when the first Database
library came out for Ruby, so
probably this is as far as I can go on this.

When you create a thread
   thread1 = Thread.new { your query #1 here }
   thread2 = Thread.new { your query #2 here }
You can set up a timeout block waiting for thread1 and thread2 to join
the main thread.
You can use the Timeout library.
Looks like it be something like
    begin
      Timeout::timeout( @timeout ) do
       thread1.join; thread2.join
      end
    rescue Timeout:ERROR
      tread1.kill; thread2.kill;
    end
I've not tested the code above, but definitely doable in Ruby.
