I noticed that following attributes are missing from
'os.path' module in Jython 2.2a1 but they are available
at least on Python 2.4. 

altsep
curdir
extsep
pardir
pathsep
sep

Having these attributes would make it easier to write
code that works both in Python and Jython. Fortunately
'sep' and 'pathsep' are available in 'os' module and
others are not that important because, AFAIK, they have
same values at least on Windows, Linux and modern Macs.
