The KLT threading model is a newly released model on NonStop. It implements
kernel-level threading. KLT provides much closer threading to what OpenSSL
uses for Linux-like threading models. KLT continues to use the pthread library
API. There is no supported 32-bit or Guardian builds for KLT. Note: KLT is
not currently available but is planned for post-2024.
