Jim Baker started to port over PyPy's support.  The result so far is
[jython-home]/LIb/_rawffi.py and
[jython-home]/Lib/test/test__rawffi.py.  It looks like Jim was porting
test by test from the same file in PyPy (test__rawffi.py).  If you are
already familiar with PyPy's approach this stuff should look pretty
familiar.  We are using JNA as the internal part for the parts that
PyPy does in rpython, then we plan to just use the pure python parts
from PyPy as-is.  I still hope to freeze this Friday - do you think
you could have it together by then?  It would be great if you could,
it was a hard decision for me to drop it.

BTW, even if you do just push it forward without it being enough for
Friday, I think we'd still like to get it in for 2.5.1.

Thanks!
