CGI::Session::PStore#restore method

Recently, I've run into the problem with CGI session resetting. I'm 
using CGI::Session::PStore session manager. Looking at the following 
method:

      def restore
         unless @hash
           @p.transaction do
             begin
               @hash = @p['hash']
             rescue
               @hash = {}
             end
           end
         end
         @hash
       end

from the lib/cgi/session/pstore.rb file made me wonder what this 
begin/rescue is doing there. After a little bit of investigation, it 
turned out that PStore#[] method never throws an exception inside the 
transaction scope. So this piece of code doesn't make any sense at all. 
I'm proposing to fix it by applying this patch:

+           @hash = @p['hash'] || {}
           end
         end
         @hash

BTW, it fixes my original session reset problem nicely.
