Issue1664366

javaos unconditionally imports javapath as os.path
This breaks several things as javaos doesn't properly implement several os.path functions, relies on the underlying live system at the moment instead of purely definitional expectations, and fundamentally provides a different model of os.path than CPython does (always loads javapath=os.path, instead of conditionally making os.path=ntpath, posixpath, macpath, etc).

You can see the full details in my comments to the bug

This patch also fixes
[1661700] os.path.abspath raises IOException if drive not accessible

See my comments on that bug as well for why
http://sourceforge.net/tracker/index.php?func=detail&aid=1661700&group_id=12867&atid=112867

This likely fixes other problems as well.

Unfortunately the platform specific path modules expect os.stat to work properly, which isn't the case due to Java limitations.  Until that's addressed we can't just use them as javapath has Java specific workarounds that don't use stat.

oops -- I didn't notice this was closed.
