require 'timeout'

Thread.new do
    begin
        Timeout.new(10) do
            sleep(11)
        end
    rescue Timeout::Error
        puts "trying again"
        retry
    end
end

loop { sleep(1) }

This kills it on FreeBSD 4.11, but not on Linux 2.6.13. Note that
"Timeout.new" is invalid, but that's how I got it to do it in the first
place.

I was trying to make use of Timeouts to do a hacky timer system (eg, a
block that's run every N seconds). I figured by doing:

Thread.new do
    begin
        Timeout::timeout(N) { sleep(N + 1) }
    rescue Timeout::Error
        # some code to run every N seconds
        retry
    end
end

I could accomplish that. By making the mistake Timeout.new instead of
Timeout::timeout is how I originally caused this to happen. After
changing it to Timeout::timeout it does work as I intended.
