Warning messages using PStore in Ruby 1.91

Hi all,

I’m running Ruby 1.91 and I’m getting the following two warning messages
when using PStore:

C:/tools/ruby19/lib/ruby/1.9.1/pstore.rb:134: warning: instance variable
@thread_safe not initialized

C:/tools/ruby19/lib/ruby/1.9.1/pstore.rb:452: warning: method redefined;
discarding old marshal_dump_supports_canonical_option?

Anyone else been seeing these?
