Attached is an implementation of ``getcallargs``.

@Andreas, looks straightforward. I see you had to workaround this issue in https://github.com/beachmachine/django/commit/1c6104cb8f395bfa344da035b5b78c30a6037a9d, so we really should make this fix.

Target beta 4

This issue shouldn't be marked as resolved.  Django uses getcallargs to pass django debugging information back the developer.  If you comment out getcallargs then Django is unable to give you exception details to help you resolve any issues you encounter developing on Django.  The exception that you end up getting provides no details about Django error and only displays that the Jython getcallargs is not defined.  I would like help to get this resolved.

This issue is not yet resolved, it has simply been accepted as a problem.

The fix is of course very straightforward, so we should apply this ASAP.
