With source from a few minutes ago most of the failures are gone:

        http://www.netbsd.org/~ad/run6.txt

Those remaining appear to be due to the test suite doing something silly, or
amusingly, not being POSIX compliant itself. The spew below seem to be from
real bugs in NetBSD.

Nearly all of the threads interfaces are implemented. Missing is process
shared synchronization and priority inheritance (at user level). From the
OS implementors view those are effectively the same bit of code. There are
some odd function calls that it would be nice to add, but that's about it.

To describe NetBSD's pthread library as "not POSIX compatible" is stretching
the truth quite a bit.
