I was talking to the debian64 maintainers yesterday (in
#debian-amd64). They told me it seams MythTV is the only big
application using pthread_rwlock_* and noone else has reported the
problem before. They asked me if I could open a bug to the debian
glibc package about it (http://bugs.debian.org/glibc). As I'm not
really able to describe the error and you're the only one who
understands what's going on there, could you just please open the bug?
They really wanted to help me yesterday, but I wasn't able to provide
more information.
They also told me that on pure64 always NPTL is used and linux threads
are never used. Perhaps you understand more of it ;)

I'm always compiling all the packages with gcc-3.4 as it supports
-march=k8. I've never had any problems so far since I use your pthread
patch.
