   Well, if we are going to bump the major for most of our libraries I
   guess we can also depend on __thread working for those libraries.
 

Current it is not safe to make libraries to use __thread unless libc_r 
is fixed firstly to support
tls, libthread_xu is not a problem because it is designed from ground 
for that idea.
I am still working on rtld since some locking code is missing in 
previous patch.

   I am still trying to figure out the best way to allow work to proceed
   on libc v5 and other required bumps without impacting current users.
