Subject: Thoughts on loops and stacks

I was thinking about some of the design issues in my dice.rb script:

    http://www2.codegnome.org:59321/scripting/showscript.php?script=dice.rb

and one of the major issues is queueing. I'd like to ensure that
selecting multiple URLs doesn't overwrite the current contents from the
previous X selection, so I was thinking what I needed to do was
implement a FIFO stack.

My main issues are that I don't want to miss any X selections, but at
the same time I don't want ruby running in such a tight loop that it
sucks up excessive CPU time.

Right now, I'm doing:

    loop do;
	# grab X selection
    	# time-consuming WWW::Mechanize stuff with selection
	sleep 0.3
    end

which isn't really event driven. So, if I select several URLs in quick
succession, only the URL in the X selection *the next time ruby looks at
it* gets handled.

Suggestions?
