I've built a small web service using webrick. The service runs on a separat=
e
thread. When it gets an exception it, apparently, dies...it being the
thread.

Is there a way to catch the exception without the thread exiting? The code
is opening a file so I wrapped it in a begin/rescue block, but it doesn't
seem to help.

    begin
      File.open(buffer[:file_name], 'a') do |f|
        f.print(buffer[:text])
      end
    rescue Exception
      @logger.error("could not write message\n  #{$!}\n  file
>#{buffer[:file_name]}<\n  message >#{buffer[:text]}<")
    end

If the file is invalid I think the thread dies -- but I don't see a message
anywhere.
