This opens up very important questions.  How do we smoothly make
the transition?  What is the appropriate threading library for each
platform?  Should 'libpthread' be a symlink, or should a library be
renamed?  How do we answer these last two questions in a consistent
fashion?  Where does libmap fit in?
