Subject: Re: how does drb work

Don't get me wrong, I like drb, but as you said it's complex, and people 
usually want simple solutions ;)

I even used drb as lock that would not allow program to be run if 
another instance was running

require 'drb'

begin
   DRbServer.new("drb://localhost:23422",nil)
rescue Exception
   puts "only once!"
   exit 1
end

but that doesn't change the fact that it's often confuising, blocking, 
have some memory problems, and it's slow
