Subject: Re: pthread_getspecific(3) with negative key

POSIX says this:
| The effect of calling pthread_getspecific() or pthread_setspecific()
| with a key value not obtained from pthread_key_create() or after key
| has been deleted with pthread_key_delete() is undefined.
So no check for a valid key is required.
Thanks,
