New issue 50: cached_setup needs to cache correctly
http://bitbucket.org/hpk42/py-trunk/issue/50/cached_setup-needs-to-cache-correctly

Description:
  Ronny pointed out that cached_setup does not work how one might assume: 
{{{
#!python
def pytest_funcarg__one(request):
      return request.cached_setup(lambda: 42)
def pytest_funcarg__two(request):
      return request.cached_setup(lambda: 17)
def test_hello(one, two):
     # one and two will both be 42!
}}}

this is because the 'request' object is re-used across all function argument setups and the funcarg name is not stored on it.  Needs to be better document or fixed - likely adding 'funcargname' as a key is the best approach even if it complicates the implemnetation a bit.
