+1, let's make this distinction. Keep os.uname with the new change; and
make platform.uname go back to being Java information. This is why we have
the platform module, vs the os module.

I would keep this distinction for Jython 3.

Agreed about the constant pain.

If we had the chance to go back in time to fix this for 2.7.0, I would have
made os.name be the underlying OS (eg 'posix' instead of 'java'). The os
module should be about the underlying OS - it mostly is. So definitely we
should fix for Jython 3.

+1

Supporting os.uname on Windows make sense.
