You can create thousands with libkse.  You'll really
only be limited by memory -- unless you create a lot
of threads as PTHREAD_SCOPE_SYSTEM, in which case you'll
likely have similar limitations as libthr.  As julian
said, libkse can be compiled to be in 1:1 mode, so if
you build it that way (the default is M:N, not 1:1),
you'll also be limited.
