Subject: Re: limiting how long a method is permiited to run

On windows, without having to go to the level of processes or using 
fork, (as it doesn't work on windows), is there a way to timeout either 
a call to system or a call using the backtic sytax as in the following 
logical code which doesn't work?

require 'timeout'

begin
	status = Timeout::timeout(1) do
		`notepad`
		while(true)
			puts "this is to fill up the rest of the time"
		end
	end
rescue Timeout::Error
	puts "Here is the code from rescue"
end

puts "And here is code after the begin/end block"
