DragonFly’s Light Weight Process abstraction is now finished and
working via libthread_xu but the default threading library is not
quite ready to be changed from libc_r yet. All threaded programs now
link against an actual ‘libpthread’ which is a softlink to libc_r or
libthread_xu, allowing the new threading library to be tested more
fully.
