The _kernel_ thread work is limping along. It hasn't quite come to a
halt. 8-)

The code in libc_r passes all my local tests that include some rather
big applications with performance comparisons of the same code running
under OSF/1, including some X based. There have been changes
recently to allow for kernel threading as an alternative, but these
are insignificant.

The elf, posix (realtime), alpha and sparc things won't destabilise
the system, IMO. It looks like the microtime changes have been pretty
much digested too. As always, -current in a production environment
is a risk, but the system looks stable at present. YMMV.
