rb_thread_current not supported

I'd just like to add a comment that this one would be a great one to get fixed 
because as far as I can see, this is the only issue that stops Test::Unit from 
working. I discovered this when experimenting with the strscan tests from the 
MRI. I 
was pleasantly surprised to see that Test::Unit seems to 'just work' when the 
tests 
pass. However when a test fails, pp is used for reporting. I did a bit of 
digging 
and worked out that pp is using thread-local variables to preserve state. That 
is 
where the rb_thread_current reference comes in. As a **temporary** hack I re-
implemented 2 methods in PP as below - and I can now run the strscan Test::Unit 
tests without modification. Oh happy day! 

require 'pp'
class PP
  # TEMPORARY HACK - NOT THREAD SAFE
  @threadvars = {}
  def guard_inspect_key
   @threadvars = {} unless @threadvars
     if @threadvars[InspectKey] == nil
      @threadvars[InspectKey] = []
     end
     save = @threadvars[InspectKey]
     begin
      @threadvars[InspectKey] = []
      yield
     ensure
      @threadvars[InspectKey] = save
     end    
   end

   def pp(obj)
     id = obj.__id__
     @threadvars = {} unless @threadvars
     if @threadvars[InspectKey].include? id
       group {obj.pretty_print_cycle self}
       return
     end
     begin
       @threadvars[InspectKey] << id
       group {obj.pretty_print self}
     ensure
       @threadvars[InspectKey].pop unless PP.sharing_detection
     end
   end
end
