At present libpthread implements the POSIX Threads functions and some
additional non-portable extenions. We don't deviate much from pthreads.
If your new feature is quite different then it might not be a match for
libpthread or glibc.

You should start by making your code available perhaps in a distinct
project or as a glibc add-on and discussing further once you have more
concrete information to present. Consider carefully the license of your
code and all things you'll need for a good contribution:
https://sourceware.org/glibc/wiki/Contribution%20checklist

I know it's quite a lot to review, but license and copyright assignment
are the top two things to get out of the way if you're looking to
contribute to the project at any level.

We are also starting to discuss a non-pthread experimental library
for exposing executaion agent interfaces to be used by higher level
frameworks whose requirements don't directly map well onto POSIX
threads. Your synchronization object might be suited to such an
experimental library, but again it's hard to say without any more
information.

Cheers,
Carlos.
