Yes, its up to the user to ensure that there are enough POSIX keys 
available. This is quite a pain.

Why is no TLS value used (instead of the POSIX key)?

It would be possible to make the pthread_key_t self-contained, however, 
for the thread-specific value you need some system provided storage 
(currently the workspace).
