I understand.
Thank you for explaining.

The thread API I am implementing differs much to pthreads, which
required a lot of glue code translating one API to another and felt
hand wrenching.
On the other hand implementing it on bare syscalls was refreshingly
simple.
But if I do not want to implement the whole libc with it, I will need
to revisit this idea.
C'est la vie...
