Thanks for doing this, its valuable feedback.

We're trying to work through addressing those. Some of them are from
versions in meta-oe where there is a fix for the error in OECore (such
as the libgcc linker hash style).

Can you file a bug about this problem please. I think we need to go
through the code paths in shadow and ensure its locking is sane. I took
a quick look at the code and was left wondering what lckpwdf() does for
example. Scott, could you take a look at this?

This is something to raise with the meta-oe maintainers. I think there
isn't a problem in OECore.

Yes, this isn't good. Could you file a bug report on this please?

Makes sense and its something raise with the meta-ti layer maintainers
which I think I've seen elsewhere.

I think these errors should be fixed by recent changes. If not I'd be
interested in the full console log please.
