Well.  This is how I understand the difference between 2.0 and -current
- "-current" will have all the ugly things in it, while 2.0 is known
to work (the short version).

That's what I did with the pre-2.0 releases: test it thoroughly on 
my test sparc64 system.  The "production" system wasn't upgrade until
some time after the release - and I had no crashes on the test system
(I had no crashes on the production system either, for the longest time
- but then I upgraded something in userland, and the system started
crashing on me).

OTOH, this nice "it's all my own fault" discussion doesn't really answer 
the open question "is it a good thing to backport the -current thread 
fixes (library and kernel) to 2.0, or will it make everything break 
even worse"...

Waiting for advice, I've recompiled libpthread with the patch (went in
fairly smooth) and -DPTHREAD_MLOCK_KLUDGE, and it doesn't crash
the machine immediately :-) - now I'll need to wait and see what will 
happen over the next few days...
