[OpenAFS] 1.6 major feature: pthreads = on

[omalleys@msu.edu]

Pthreads appears to be the only major feature in the 1.6 release.  It  
needs to be on by default since you are -calling- it a major release  
and people -expect- some issues. You might as well have them with your  
MAJOR feature.  Otherwise it is just a lame fork of the 1.5.x branch  
you might as well just call it 1.5.x instead of renaming it 1.6. It  
isn't like the lwp code is yanked out. If people want 1.6 with lwp  
they can recompile.

But you really -should- announce something new with a major version release.
