KSE, libpthread & libthr: almost newbie question

[Lev Serebryakov]

Hello ,

   I've was sure, that both libpthread and libthr use KSE to make multithreading. They use KSE in different ways: libpthread uses N:M model and libthr uses 1:1 model, but bot use KSE to work.
   How will be possible to sue these libraries (read: multithreaded programs) when KSE will be optional, on kernel without KSE?!
