32 .Nd "alternative POSIX threads library"
40 library provides an alternative 1:1 implementation of the
42 library interfaces for application threading.
43 While applications may be linked directly against
45 system administrators are offered maximum flexibility by linking against
49 to select the threading implementation on a per-application basis.
54 has been optimized for use by applications expecting system scope thread
55 semantics, and can provide significant performance improvements.
