Does the user get the correct error code in the current code ?

Do any other parts of the POSIX API suffer from this problem or is it 
just threads (tasks!) ?

This is also the case with User Extensions and the drivers table. You 
can add drivers after starting, but the number is fixed. Any others ?

I can raise a PR for this and list all the areas that need to be looked at.

I have not looked at the POSIX implementation so far :-). Are keys 
handled in one spot ?
