Understood. 

Do you/others happen to know who is the maintainer of the
TLS emulation?  I tried a simple test case that works
with the native TLS support, but it SEGV's when using
TLS emulation.  Perhaps a cockpit error on my part, but
I'd like to see if I can use the TLS emulation for our
purposes, and a first step is to get the example to work.
