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.
